[0033] The following detailed description of example embodiments refers to the accompanying drawings.The same reference numbers in different drawings may identify the same or similar elements.

[0034] Conventional photonic integrated circuits (PICs) (e.g., including interferometers) typically include multiple light transmission structures (e.g., waveguides) that transmit light. In many cases, light transmitted through a first light transmission structure of the PIC needs to be phase-matched with light transmitted through a second light transmission structure of the PIC. Therefore, the PIC typically includes one or more resistive microheaters (e.g., integrated metal components) to heat portions of the first light transmission structure and / or the second light transmission structure. By supplying heat, the optical properties (such as refractive index) of the first light transmission structure and / or the second light transmission structure can be adjusted, which can promote phase matching of light transmitted through the first light transmission structure and light transmitted through the second light transmission structure.

[0035] However, including one or more resistive microheaters in a PIC increases the design complexity of the PIC. For example, the PIC needs to be designed to allow additional processing to integrate the one or more resistive microheaters within the PIC, allow electrical circuits to be connected to the one or more resistive microheaters, and / or allow for additional heat generated by the circuits. Therefore, due to these complexities, PICs that include one or more resistive microheaters are typically limited to single layer implementations. This limits the possible size and shape of the PIC, which prevents the PIC from being used in some applications (e.g., applications that require a multi-layer PIC).

[0036] Some embodiments described herein provide a photonic system including a light source and a photonic structure. The photonic structure includes a light transmission structure and a light absorption structure. The light transmission structure is configured to transmit light associated with a first wavelength range, and the light absorption structure is configured to absorb light associated with a second wavelength range. Therefore, the light source is configured to provide one or more light beams with a wavelength within the second wavelength range to the light absorption structure. This causes the light absorption structure to generate heat and provide heat to the light transmission structure. Therefore, the heat changes one or more optical properties of the light transmission structure (such as the refractive index of the light transmission structure).

[0037] In this way, one or more optical properties of the light-transmitting structure are "tuned" by heat supplied by the light-absorbing structure (e.g., as described above, this promotes phase matching). Because the heat is provided via optical heating, the photonic system can provide more precise temperature control and faster response (on / off) times (e.g., by controlling the on / off times of the light source, the optical power of the light source, and / or other properties of the light source) than provided by a resistive microheater (e.g., which has a slower response time and less precise temperature control). Further, the use of the light-absorbing structure reduces the design complexity of the photonic structure by eliminating the need for wiring circuits for the resistive microheater and compensating for the thermal effects of the circuit. Therefore, due to the reduced design complexity, some embodiments described herein facilitate the design of multi-layer photonic structures including multiple light-transmitting structures and multiple light-absorbing structures, which enables the photonic transmission structure to be used in some applications (e.g., applications requiring multi-layer photonic structures) that would not otherwise use conventional PICs.

[0038] Figure 1 is a diagram of an example photonic system 100 described herein. Figure 1 As shown, the photonic system 100 may include a photonic structure 102. The photonic structure 102 may be, for example, an optical logic gate, an optical switch, an optical amplifier, an optical modulator, and / or a frequency comb.

[0039] like Figure 1 As shown, the photonic structure 102 may include a substrate 104, one or more layers 106, a cladding material 108, a light absorbing structure 110, and / or a light transmitting structure 112. The substrate 104 may include a substrate 104 formed thereon. Figure 1 The substrate 104 may be a transmissive substrate (such as a glass substrate, a silicon substrate, or a germanium substrate). Figure 1 As further shown, one or more layers 106 (such as Figure 11 to 106-3 in FIG. 104) can be disposed on the substrate 104 (eg, on the top surface of the substrate 104). The cladding material 108, the light absorbing structure 110, and / or the light transmitting structure 112 can be included in one or more layers 106, as described herein.

[0040] The cladding material 108 can be configured to confine light (e.g., transmit light through the light-transmitting structure 112, as further described herein). In some embodiments, the cladding material 108 can be configured to thermally conduct heat (e.g., conduct heat generated and provided by the light-absorbing structure 110 to the light-transmitting structure 112, as further described herein). The cladding material 108 can include, for example, an oxide material (e.g., a silicon dioxide material), a polymer material (e.g., a siloxane polymer material), or another cladding material.

[0041] The light absorbing structure 110 may be configured to absorb light. For example, the light absorbing structure 110 may be configured to absorb a specific percentage of light incident on the light absorbing structure 110 (e.g., a percentage amount of light that satisfies a percentage threshold), such as a specific percentage of light less than or equal to 20%, 35%, 60%, or 65%. The light absorbing structure 110 may include an absorptive thin film structure (e.g., including one or more absorptive films), an absorptive glass, an absorptive pigment or dye, or another type of light absorbing structure. In some embodiments, the light absorbing structure 110 may include at least one of the following: tantalum, nickel, copper, aluminum, niobium, silver, zinc, chromium, hafnium, thallium, silicon, niobium, tantalum, silyl, germanium, silicon germanium, metal oxides, substoichiometric nitrides, and / or any other material configured to absorb light.

[0042] The light transmission structure 112 may be configured to transmit light. For example, the light transmission structure 112 may include at least a portion of the following structures of the photonic structure 102: a waveguide structure, an interferometer structure, an optical switch structure, an optical resonator structure, and / or another light transmission structure. In some embodiments, the light transmission structure 112 may include at least one of the following materials: a non-alkaline oxide solution including niobium cations (niobium tantalum oxide solution, niobium titanium oxide solution, and / or niobium tantalum titanium oxide solution, as well as other examples), an amorphous silicon material, a hydrogenated amorphous silicon material, a nitride-based material, an oxide-based material, a metal material, or a semiconductor material, as well as other examples.

[0043] In some embodiments, the light absorbing structure 110 and / or the light transmitting structure 112 may be disposed within the photonic structure 102. For example, Figure 1As shown, the light absorbing structure 110 and the light transmitting structure 112 can be disposed in different layers 106 of one or more layers 106 of the photonic structure 102. Thus, the light absorbing structure 110 can be positioned within the photonic structure 102 such that the light absorbing structure 110 is adjacent to at least one surface of the light transmitting structure 112. For example, Figure 1 As shown, the light absorbing structure 110 may be included in a layer (e.g., layer 106-3) of the photonic structure 102, which is disposed on another adjacent layer (e.g., layer 106-2) of the photonic structure 102 that includes the light transmitting structure 112. Therefore, the light absorbing structure 110 is at least adjacent to the top surface of the light transmitting structure 112 (e.g., the light absorbing structure 110 is closer to the top surface of the light transmitting structure 112 than to another surface of the light transmitting structure 112). Additionally or alternatively, the light absorbing structure 110 may be adjacent to at least one surface of the light transmitting structure 112 when the distance between the light absorbing structure 110 and at least one surface of the light transmitting structure 112 satisfies a distance threshold value (which may be less than or equal to 100 nanometers (nm)).

[0044] In some embodiments, the cladding material 108 can be disposed within the photonic structure 102, such as within at least one of the one or more layers 106. For example, Figure 1 As shown, each of the one or more layers 106 (eg, layers 106-1 to 106-3) may include a cladding material 108. In some embodiments, as shown in FIG. Figure 1 As further shown, at least a portion of the cladding material 108 may be disposed between the light absorbing structure 110 and the light transmitting structure 112 (eg, between at least one surface of the light absorbing structure 110 and at least one surface of the light transmitting structure 112 ).

[0045] In some embodiments, the light-transmitting structure 112 can be configured to transmit light associated with a first wavelength range within the light-transmitting structure 112. For example, the light-transmitting structure 112 can be configured to transmit light having a wavelength within a wavelength range of 1200-1600 nanometers (nm) (e.g., light having a wavelength greater than or equal to 1200 nm and less than or equal to 1600 nm). Further, in some embodiments, the light-absorbing structure 110 can be configured to absorb light associated with a second wavelength range. For example, the light-absorbing structure 110 can be configured to absorb light having a wavelength within a wavelength range of 800-1199 nm (e.g., light having a wavelength greater than or equal to 800 nm and less than or equal to 1199 nm).

[0046] In some embodiments, the light transmission structure 112 can be configured to be capable of transmitting light associated with a second wavelength range. For example, the light transmission structure 112 can be configured to be capable of transmitting (transmissive) light having a wavelength within a wavelength range of 800-1199 nm. In this way, the light associated with the second wavelength range can not interfere with or otherwise affect the transmission of light associated with the first wavelength within the light transmission structure 112 (e.g., when the light associated with the second wavelength range passes through the light transmission structure 112). Additionally or alternatively, the cladding material 108 can be configured to be capable of transmitting light associated with the second wavelength range. In this way, light associated with the second wavelength can propagate through the cladding material 108 to the light transmission structure 112 (e.g., as further described herein) with little to no loss of light energy.

[0047] In some embodiments, the photon system 100 may include a light source 114. The light source 114 may be a laser device, a light emitting diode (LED) lighting device, an incandescent lamp device, a fluorescent lamp device, a halogen lamp device, and / or other types of light sources. The light source 114 may be configured to provide one or more light beams 116 each having a wavelength within a second wavelength range. For example, Figure 1 As shown, the light source 114 can provide one or more light beams 116, each light beam having a wavelength within a wavelength sub-range of a second wavelength range, such as a wavelength sub-range of 850-949 nm (e.g., one or more light beams 116 can have wavelengths each greater than or equal to 850 nm and less than or equal to 949 nm).

[0048] In some embodiments, the light source 114 can be disposed on a surface of the photonic structure 102. For example, Figure 1 As shown, the light source 114 can be disposed on the top surface of the photonic structure 102. Figure 1 As further shown, the light source 114 can be configured to provide one or more light beams 116 to an area 118 of a surface of the photonic structure 102 (e.g., an area 118 of a top surface of the photonic structure 102). In some embodiments, the area 118 can include an anti-reflective coating configured to reduce reflection of light associated with the second wavelength range. In this way, when the one or more light beams 116 are incident on the area 118, the area 118 reduces the amount of the one or more light beams 116 reflected from the area 118 of the photonic structure 102 (e.g., compared to when the one or more light beams 116 are incident on an area of ​​the surface of the photonic structure 102 without the anti-reflective coating). Therefore, the area 118 can facilitate the one or more light beams 116 to enter the photonic structure 102 with little loss of light energy.

[0049] In some embodiments, the light source 114 can be configured to provide one or more light beams 116 to the light absorbing structure 110 (e.g., via the region 118 of the photonic structure 102). For example, the light source 114 can be configured to provide the one or more light beams 116 such that the one or more light beams 116 enter the photonic structure 102 via the region 118 of the top surface of the photonic structure 102 and propagate through a portion of the cladding material 108 (e.g., between the light absorbing structure 110 and the light transmitting structure 112) to the light absorbing structure 110 in the layer 106-3.

[0050] In some embodiments, the light absorbing structure 110 may be configured to generate heat 120 when a light beam having a wavelength within a second wavelength range is incident on the light absorbing structure 110. For example, when one or more light beams 116 propagate to and are incident on the light absorbing structure 110, the light absorbing structure 110 may be configured to generate heat 120. The heat 120 generated by the light absorbing structure 110 may be within a thermal range, such as 20 degrees Celsius (° C.) to 450° C. (e.g., the heat 120 may be greater than or equal to 20° C. and less than or equal to 450° C.).

[0051] In some embodiments, the light absorbing structure 110 can be configured to provide heat 120 to the light transmitting structure 112. For example, the light absorbing structure 110 can provide heat 120 to the light transmitting structure 112 because the light absorbing structure 110 is adjacent to at least one surface of the light transmitting structure 112 (e.g., the light absorbing structure 110 is close to at least one surface of the light transmitting structure 112, such as within 100 nm of the light transmitting structure 112). Additionally or alternatively, the cladding material 108 can be configured to thermally conduct heat, and thus, the portion of the cladding material 108 between the light absorbing structure 110 and the light transmitting structure 112 can conduct heat 120 from the light absorbing structure 110 to the light transmitting structure 112.

[0052] In some embodiments, one or more optical properties of the light transmitting structure 112 may change due to the light absorbing structure 110 generating heat and providing heat 120 to the light transmitting structure 112. For example, the refractive index of the light transmitting structure 112 may change due to the light absorbing structure 110 generating heat and providing heat 120 to the light transmitting structure 112.

[0053] As mentioned above, Figure 1 is provided as an example. Other examples may be related to Figure 1 In practice, the photonic structure 102 may include additional layers and / or structures, fewer layers and / or structures, different layers and / or structures, or different layers and / or structures. Figure 1 The layers and / or structures shown are arranged differently.

[0054] Figure 2 is a diagram of an example photonic system 200 described herein. Figure 2 As shown, the photonic system 200 may include a photonic structure 202, which may be similar to that described herein with respect to Figure 1 For example, the photonic system 200 may include a substrate 204, one or more layers 206, a cladding material 208, a light absorbing structure 210, and / or a light transmitting structure 212, which are described herein. Figure 1 The photonic system 200 may be the same or similar to the corresponding elements of the photonic structure 102 described herein. In some embodiments, the photonic system 200 may include a light source 214, which may be the same as described herein with respect to Figure 1 The light sources 114 described are the same or similar.

[0055] In some embodiments, the light transmitting structure 212 and the light absorbing structure 210 may be disposed in different layers 206 of the one or more layers 206 of the photonic structure 202. For example, Figure 2 As shown, the light absorbing structure 210 may be included in a layer 206 (e.g., layer 206-1) of the one or more layers 206 of the photonic structure 202, and the light transmitting structure 212 may be included in another layer 206 (e.g., layer 206-2) of the one or more layers 206 of the photonic structure 202. In some embodiments, the light absorbing structure 210 may be disposed on at least one surface of the light transmitting structure 212 (e.g., the light absorbing structure 210 may contact at least one surface of the light transmitting structure 212 without any cladding material 208 disposed between the light absorbing structure 210 and the light transmitting structure 212). For example, as Figure 2 As further shown, the light absorbing structure 210 may be disposed on a bottom surface of the light transmitting structure 212 .

[0056] In some embodiments, the light source 214 can be disposed on a surface of the photonic structure 202. For example, Figure 2 As shown, the light source 214 can be disposed on the top surface of the photonic structure 202. Figure 2 As further shown, the light source 214 can be configured to provide one or more light beams 216 (eg, similar to those described herein) to a region 218 of a surface of the photonic structure 202 (eg, a region 218 of a top surface of the photonic structure 202). Figure 1 In some embodiments, region 218 may include an anti-reflective coating (e.g., to provide an anti-reflective coating as described herein). Figure 1 118 described above).

[0057] In some embodiments, the light source 214 can be configured to provide one or more light beams 216 to the light absorbing structure 210 (e.g., via transmission through the light transmitting structure 212). For example, the light source 214 can be configured to provide the one or more light beams 216 so that the one or more light beams 216 enter the photonic structure 202 via a region 218 of the top surface of the photonic structure 202 and propagate through a portion of the cladding material 208 and the light transmitting structure 212 (e.g., because the cladding material 208 and the light transmitting structure 212 are arranged in a manner similar to that described herein). Figure 1 The cladding material 108 and light transmitting structure 112 described above can transmit light associated with the second wavelength range) to the light absorbing structure 210 in layer 206-3 in the same or similar manner.

[0058] In some embodiments, the light absorbing structure 210 can be configured to generate heat 220 (e.g., in a manner similar to that described herein) when a light beam having a wavelength within a second wavelength range is incident on the light absorbing structure 210. Figure 1 In some embodiments, the light absorbing structure 210 can be configured to provide heat 220 to the light transmitting structure 212. For example, the light absorbing structure 210 can provide heat 220 to the light transmitting structure 212 because the light absorbing structure 210 is disposed on at least one surface of the light transmitting structure 212. In some embodiments, one or more optical properties of the light transmitting structure 212 can change (e.g., in a manner similar to that described herein with respect to the light absorbing structure 210 generating heat 220 and providing heat 220 to the light transmitting structure 212). Figure 1 The light transmitting structure 112 described above may be used in the same or similar manner).

[0059] As mentioned above, Figure 2 is provided as an example. Other examples may be related to Figure 2 In practice, the photonic structure 202 may include additional layers and / or structures, fewer layers and / or structures, different layers and / or structures, or different layers and / or structures.

[0060] Figure 3 is a diagram of an example photonic system 300 described herein. Figure 3 As shown, the photonic system 300 may include a photonic structure 302, which may be similar to that described herein with respect to Figure 1 For example, the photonic system 300 may include a substrate 304, one or more layers 306, a cladding material 308, a light absorbing structure 310, and / or a light transmitting structure 312, which are described herein. Figure 1The photonic system 300 may be the same or similar to the corresponding elements of the photonic structure 102 described herein. Figure 1 The light sources 114 described are the same or similar.

[0061] In some embodiments, the light transmitting structure 312 and the light absorbing structure 310 may be disposed in different layers 306 of the one or more layers 306 of the photonic structure 302. For example, Figure 3 As shown, the light absorbing structure 310 may be included in a layer 306 (e.g., layer 306-1) of the one or more layers 306 of the photonic structure 302, and the light transmitting structure 312 may be included in another layer 306 (e.g., layer 306-2) of the one or more layers 306 of the photonic structure 302. In some embodiments, the light absorbing structure 310 may be disposed on at least one surface of the light transmitting structure 312 (e.g., the light absorbing structure 310 may contact at least one surface of the light transmitting structure 312 without any cladding material 308 disposed between the light absorbing structure 310 and the light transmitting structure 312). For example, as Figure 3 As further shown, the light absorbing structure 310 may be disposed on a bottom surface of the light transmitting structure 312 .

[0062] In some embodiments, the photon structure 302 may include a light reflecting structure 322 disposed within the photon structure 302. For example, Figure 3 As shown, the light reflecting structure 322 can be disposed within a layer 306 (e.g., layer 306-1) of the one or more layers 306 of the photonic structure 302. The light reflecting structure 322 can be configured to reflect light. For example, the light reflecting structure 322 can be configured to reflect a specific percentage of light incident on the light reflecting structure 322 (e.g., a percentage amount of light that satisfies a percentage threshold), such as 20%, 35%, 60%, or 65%. The light reflecting structure 322 can include a set of metal mirror layers (e.g., including silver, gold, or another reflective metal), a set of dielectric mirror layers (e.g., alternating hydrogenated silicon layers and silicon dioxide layers), and / or another set of layers configured to reflect light.

[0063] In some embodiments, the light reflecting structure 322 can be configured to reflect light associated with a second wavelength range (eg, as described herein with respect to Figure 1). For example, the light reflecting structure 322 can be configured to reflect light having a wavelength within a wavelength range of 800-1199 nm (e.g., light having a wavelength greater than or equal to 800 nm and less than or equal to 1199 nm). In some embodiments, the light reflecting structure 322 can be configured to reflect a light beam (e.g., the light beam is associated with the second wavelength range and provided by the light source 314, as described herein) toward the light absorbing structure 310 when the light beam is incident on the surface of the light reflecting structure 322 within a specific incident angle range (e.g., within an angle range of 30 degrees of the normal to the surface of the light reflecting structure 322).

[0064] In some embodiments, the light source 314 can be disposed on a surface of the photonic structure 302. For example, Figure 3 As shown, the light source 314 can be disposed on the right side surface of the photonic structure 302. Figure 3 As further shown, the light source 314 can be configured to provide one or more light beams 316 (e.g., which are similar to those described herein) to an area 318 of the surface of the photonic structure 302 (e.g., an area 318 of the right side surface of the photonic structure 302). Figure 1 In some embodiments, region 318 may include an anti-reflective coating (e.g., to provide an anti-reflective coating as described herein). Figure 1 118 described above).

[0065] In some embodiments, the light source 314 can be configured to provide one or more light beams 316 to the light absorbing structure 310 (e.g., via reflection from the light reflecting structure 322). For example, the light source 314 can be configured to provide the one or more light beams 316 so that the one or more light beams 316 enter the photonic structure 302 via the region 318 of the right side surface of the photonic structure 302 and pass through a portion of the cladding material 308 (e.g., because the cladding material 308 is in a manner similar to that described herein). Figure 1 The cladding material 108 described above is capable of transmitting light associated with the second wavelength range) to a surface (e.g., a top surface) of the light reflecting structure 322, which reflects one or more light beams 316 to the light absorbing structure 310 in the layer 306-1.

[0066] In some embodiments, the light absorbing structure 310 can be configured to generate heat 320 (e.g., in a manner similar to that described herein) when a light beam having a wavelength within a second wavelength range is incident on the light absorbing structure 310. Figure 1In some embodiments, the light absorbing structure 310 can be configured to provide heat 320 to the light transmitting structure 312. For example, the light absorbing structure 310 can provide heat 320 to the light transmitting structure 312 because the light absorbing structure 310 is disposed on at least one surface of the light transmitting structure 312. In some embodiments, one or more optical properties of the light transmitting structure 312 can change (e.g., in a manner similar to that described herein with respect to the light absorbing structure 110) due to the light absorbing structure 310 generating heat 320 and providing heat 320 to the light transmitting structure 312. Figure 1 The light transmitting structure 112 described above may be used in the same or similar manner).

[0067] As mentioned above, Figure 3 is provided as an example.

[0069] In some embodiments, the light transmitting structure 412 and the light absorbing structure 410 can be disposed in the same layer 406 of the one or more layers 406 of the photonic structure 402. For example, Figure 4 As shown, the light absorbing structure 410 and the light transmitting structure 412 may be included in a layer 406 (e.g., layer 406-3) of the one or more layers 406 of the photonic structure 402 (e.g., laterally adjacent to each other in the layer 406-3). In some embodiments, the light absorbing structure 410 may be adjacent to at least one surface of the light transmitting structure 412 (e.g., the distance between the light absorbing structure 410 and at least one surface of the light transmitting structure 412 may satisfy a distance threshold, which may be less than or equal to 100 nm). For example, as Figure 4As further shown, the light absorbing structure 410 may be adjacent to a right side surface of the light transmitting structure 412 .

[0070] In some embodiments, the light source 414 can be disposed on a surface of the photonic structure 402. For example, Figure 4 As shown, the light source 414 can be disposed on the right side surface of the photonic structure 402. Figure 4 As further shown, the light source 414 can be configured to provide one or more light beams 416 (e.g., which are similar to those described herein) to an area 418 of the surface of the photonic structure 402 (e.g., an area 418 of the right side surface of the photonic structure 402). Figure 1 In some embodiments, region 418 may include an anti-reflective coating (e.g., to provide an anti-reflective coating as described herein with respect to Figure 1 In some embodiments, the light source 414 can be configured to provide one or more light beams 416 to the light absorbing structure 410 (e.g., via the region 418 of the photonic structure 402). For example, the light source 414 can be configured to provide the one or more light beams 416 so that the one or more light beams 416 enter the photonic structure 402 via the region 418 of the right side surface of the photonic structure 402 and propagate through a portion of the cladding material 408 (e.g., because the cladding material 408 is disposed in a manner similar to that described herein). Figure 1 The cladding material 108 may be capable of transmitting light associated with the second wavelength range) to the light absorbing structure 410 in layer 406-3 in the same or similar manner as described.

[0071] In some embodiments, the light absorbing structure 410 can be configured to generate heat 420 (e.g., in a manner similar to that described herein) when a light beam having a wavelength within a second wavelength range is incident on the light absorbing structure 410. Figure 1 In some embodiments, the light absorbing structure 410 can be configured to provide heat 420 to the light transmitting structure 412. For example, the light absorbing structure 410 can provide heat 420 to the light transmitting structure 412 because the light absorbing structure 410 is adjacent to at least one surface of the light transmitting structure 412. In some embodiments, one or more optical properties of the light transmitting structure 412 can be changed (e.g., in a manner similar to that described herein with respect to the light absorbing structure 110) due to the light absorbing structure 410 generating heat 420 and providing heat 420 to the light transmitting structure 412. Figure 1 The light transmitting structure 112 described above may be used in the same or similar manner).

[0072] As mentioned above, Figure 4 is provided as an example. Other examples may be related to Figure 4In practice, the photonic structure 402 may include additional layers and / or structures, fewer layers and / or structures, different layers and / or structures, or different layers and / or structures.

[0073] Figure 5 is a diagram of an example photonic system 500 described herein. Figure 5 As shown, the photonic system 500 may include a photonic structure 502, which may be similar to that described herein with respect to Figure 1 For example, the photonic system 500 may include a substrate 504, one or more layers 506, a cladding material 508, a light absorbing structure 510, and / or a light transmitting structure 512, which are described herein. Figure 1 The photonic system 500 may be the same or similar to the corresponding elements of the photonic structure 102 described herein. In some embodiments, the photonic system 500 may include a light source 514, which may be the same as described herein with respect to Figure 1 The light sources 114 described are the same or similar.

[0074] In some embodiments, the light transmitting structure 512 and the light absorbing structure 510 can be disposed in different layers 506 of one or more layers 506 of the photonic structure 502. For example, Figure 5 As shown, the light absorbing structure 510 may be included in a layer 506 (e.g., layer 506-2) of the one or more layers 506 of the photonic structure 502, and the light transmitting structure 512 may be included in another layer 506 (e.g., layer 506-3) of the one or more layers 506 of the photonic structure 502. In some embodiments, the light absorbing structure 510 may be adjacent to at least one surface of the light transmitting structure 512 (e.g., the distance between the light absorbing structure 510 and at least one surface of the light transmitting structure 512 may satisfy a distance threshold, which may be less than or equal to 100 nm). For example, as Figure 5 As further shown, the light absorbing structure 510 can be adjacent to a bottom surface of the light transmitting structure 512 .

[0075] In some embodiments, the photonic structure 502 may include an additional light transmitting structure 524 disposed within the photonic structure 502. For example, Figure 5As shown, the additional light transmission structure 524 can be disposed in at least one layer 506 (e.g., layers 506-1 and 506-2) of the one or more layers 506 of the photonic structure 502. In some embodiments, the additional light transmission structure 524 can include at least one of the following materials: a non-alkaline oxide solution including niobium cations (niobium tantalum oxide solution, niobium titanium oxide solution, and / or niobium tantalum titanium oxide solution, as well as other examples), an amorphous silicon material, a hydrogenated amorphous silicon material, a nitride-based material, an oxide-based material, a metal material, or a semiconductor material, as well as other examples.

[0076] The additional light-transmitting structure 524 can be configured to transmit light. For example, the additional light-transmitting structure 524 can be configured to transmit light associated with the second wavelength range (e.g., as described herein with respect to the additional light-transmitting structure 524) within the additional light-transmitting structure 524. Figure 1 ). For example, the additional light-transmitting structure 524 can be configured to transmit light having a wavelength within a wavelength range of 800-1199 nm (e.g., light having a wavelength greater than or equal to 800 nm and less than or equal to 1199 nm). In some embodiments, the additional light-transmitting structure 524 can be configured to transmit a light beam (e.g., which is associated with the second wavelength range and provided by the light source 514, as described herein) to the light-absorbing structure 510 when the light beam is incident on the input surface of the additional light-transmitting structure 524. In some embodiments, the light-absorbing structure 510 can be positioned within the evanescent field of the additional light-transmitting structure 524. For example, a specific distance between the light-absorbing structure 510 and one or more portions of the additional light-transmitting structure 524 can be within the evanescent field of the additional light-transmitting structure 524 (e.g., to allow light energy of the light beam transmitted by the additional light-transmitting structure 524 to be transmitted from the additional light-transmitting structure 524 to the light-absorbing structure 510 via evanescent coupling).

[0077] In some embodiments, the light source 514 can be disposed on a surface of the photonic structure 502. For example, Figure 5 As shown, the light source 514 can be disposed on the right side surface of the photonic structure 502. Figure 5 As further shown, the light source 514 can be configured to provide one or more light beams 516 (e.g., which are similar to those described herein) to an area 518 of the surface of the photonic structure 502 (e.g., an area 518 of the right side surface of the photonic structure 502). Figure 1 In some embodiments, region 518 may include an anti-reflective coating (e.g., to provide an anti-reflective coating as described herein). Figure 1 118 described above).

[0078] In some embodiments, the light source 514 can be configured to provide one or more light beams 516 to the light absorbing structure 510 (e.g., via transmission of the additional light transmitting structure 524). For example, the light source 514 can be configured to provide the one or more light beams 516 so that the one or more light beams 516 enter the photonic structure 502 via the region 518 of the right side surface of the photonic structure 502 and pass through a portion of the cladding material 508 (e.g., because the cladding material 508 is in a manner similar to that described herein). Figure 1 The cladding material 108 described above can transmit light associated with the second wavelength range in the same or similar manner as described above) to an input surface (e.g., a right side surface) of an additional light transmitting structure 524, which transmits the one or more light beams 516 to the light absorbing structure 510 in layer 506-2. Additionally or alternatively, when the light absorbing structure 510 is within the evanescent field of the additional light transmitting structure 524, the light energy of the one or more light beams 516 can be transmitted from the additional light transmitting structure 524 to the light absorbing structure 510 (e.g., via evanescent coupling).

[0079] In some embodiments, the light absorbing structure 510 can be configured to generate heat 520 (e.g., in a manner similar to that described herein) when a light beam having a wavelength within a second wavelength range is incident on the light absorbing structure 510. Figure 1 10). Additionally or alternatively, the light absorbing structure 510 can be configured to generate heat 520 when light energy is transmitted from the additional light transmitting structure 524 to the light absorbing structure 510 (e.g., via evanescent coupling). In some embodiments, the light absorbing structure 510 can be configured to provide heat 520 to the light transmitting structure 512. For example, the light absorbing structure 510 can provide heat 520 to the light transmitting structure 512 because the light absorbing structure 510 is adjacent to at least one surface of the light transmitting structure 512. In some embodiments, one or more optical properties of the light transmitting structure 512 can change (e.g., in a manner consistent with the optical properties described herein) as a result of the light absorbing structure 510 generating heat 520 and providing heat 520 to the light transmitting structure 512. Figure 1 The light transmitting structure 112 described above may be used in the same or similar manner).

[0080] As mentioned above, Figure 5 is provided as an example.

Figure 5 The layers and / or structures shown are arranged differently.

[0081] Figure 6 is a diagram of an example photonic system 600 described herein. Figure 6 As shown, the photonic system 600 may include a photonic structure 602, which may be similar to that described herein with respect to Figure 1 For example, the photonic system 600 may include a substrate 604, one or more layers 606, a cladding material 608, a plurality of light absorbing structures 610 (shown as light absorbing structures 610-1 and 610-2), and / or a plurality of light transmitting structures 612 (shown as light transmitting structures 612-1 and 612-2), which are similar to those described herein. Figure 1 The photonic system 600 may be the same or similar to the corresponding elements of the photonic structure 102 described herein. In some embodiments, the photonic system 600 may include a plurality of light sources 614 (shown as light sources 614-1 and 614-2), which may be the same as described herein with respect to Figure 1 The light sources 114 described are the same or similar.

[0082] In some embodiments, the plurality of light-transmitting structures 612 may be disposed in different layers 606 of the one or more layers 606 of the photonic structure 602. For example, Figure 6 As shown, the first light-transmitting structure 612-1 can be included in a layer 606 (e.g., layer 606-3) of the one or more layers 606 of the photonic structure 602, and the second light-transmitting structure 612-2 can be included in another layer 606 (e.g., layer 606-2) of the one or more layers 606 of the photonic structure 602. Each of the plurality of light-transmitting structures 612 can be configured to transmit light associated with a particular wavelength range. For example, with respect to Figure 6 , the first light transmission structure 612-1 can be configured to transmit light associated with a first wavelength range, and the second light transmission structure 612-2 can be configured to transmit light associated with a second wavelength range (e.g., different from the first wavelength range, or alternatively, at least partially not coextensive with the first wavelength range).

[0083] In some embodiments, each light absorbing structure in the plurality of light absorbing structures 610 may be disposed within a threshold distance of a corresponding light transmitting structure 612 in the plurality of light transmitting structures 612. Figure 6As shown, the first light absorption structure 610-1 can be included in the layer 606-2 and can be disposed on at least one surface (e.g., the bottom surface) of the first light transmission structure 612-1 (e.g., disposed within a first threshold distance of the at least one surface), and the second light absorption structure 610-2 can be included in the layer 606-1 and can be adjacent to at least one surface (e.g., the bottom surface) of the second light transmission structure 612-2 (e.g., disposed within a second threshold distance of the at least one surface). Each of the plurality of light absorption structures 610 can be configured to absorb light associated with a specific wavelength range, and when a light beam having a wavelength within the specific wavelength range is incident on the light absorption structure 610, heat is generated and provided to the corresponding light transmission structure 612. For example, the first light absorption structure 610-1 can be configured to absorb light associated with a third wavelength range (e.g., different from the first wavelength range, or alternatively, at least partially not coextensive with the first wavelength range), and when a light beam having a wavelength within the third wavelength range is incident on the first light absorption structure 610-1, heat is generated and provided to the first light transmission structure 612-1. As another example, the second light absorption structure 610-2 can be configured to absorb light associated with a fourth wavelength range (e.g., different from the second wavelength range, or alternatively, at least partially not coextensive with the second wavelength range), and when a light beam having a wavelength within the fourth wavelength range is incident on the second light absorption structure 610-2, the second light absorption structure 610-2 generates heat and provides heat to the second light transmission structure 612-2.

[0084] In some embodiments, the plurality of light transmission structures 612 may be configured to be capable of transmitting light associated with a wavelength range absorbed by the plurality of light absorption structures 610. For example, each of the first light transmission structure 612-1 and the second light transmission structure 612-2 may be configured to be capable of transmitting light associated with a third wavelength range and a fourth wavelength range. Additionally or alternatively, each light absorption structure 610 may be configured to be capable of transmitting light associated with a wavelength range absorbed by other light absorption structures 610 in the plurality of light absorption structures 610. For example, the first light absorption structure 610-1 may be configured to be capable of transmitting light associated with a fourth wavelength range, while the second light absorption structure 610-2 may be configured to be capable of transmitting light associated with a third wavelength range. Additionally or alternatively, the cladding material 608 may be configured to be capable of transmitting light associated with a wavelength range absorbed by the plurality of light absorption structures 610.

[0085] In some embodiments, each of the plurality of light sources 614 can be disposed on at least one surface of the photonic structure 102. For example, Figure 6As shown, the first light source 614-1 can be disposed on the top surface of the photon structure 602, and the light source 614-2 can be disposed on the top surface of the photon structure 602. Thus, each of the plurality of light sources 614 can be configured to provide one or more light beams 616 to a specific region 618 of the plurality of regions 618 of at least one surface of the photon structure 602 (e.g., the plurality of regions 618 of the top surface of the photon structure 602). For example, Figure 6 As shown, the first light source 614-1 can be configured to provide one or more light beams 616-1 to a first area 618-1 of the top surface of the photonic structure 602, and the second light source 614-2 can be configured to provide one or more light beams 616-2 to a second area 618-2 of the top surface of the photonic structure 602. Each of the plurality of areas 618 may include an anti-reflective coating (e.g., to provide a light beam having a reflective coating similar to that described herein). Figure 1 118 described above).

[0086] In some embodiments, each of the plurality of light sources 614 can be configured to provide one or more light beams 616 to a corresponding light absorbing structure 610 in the plurality of light absorbing structures 610. For example, the first light source 614-1 can be configured to provide the one or more light beams 616-1 such that the one or more light beams 616-1 enter the photonic structure 602 via the region 618-1 of the top surface of the photonic structure 602 and propagate through the cladding material 608 and a portion of the first light transmitting structure 612-1 (e.g., because the cladding material 608 and the first light transmitting structure 612-1 are capable of transmitting light associated with the third wavelength range) to the first light absorbing structure 610-1 in the layer 606-2. As another example, the second light source 614-2 can be intended to provide one or more light beams 616-2 such that the one or more light beams 616-2 enter the photonic structure 602 via an area 618-2 of the top surface of the photonic structure 602 and propagate through a portion of the cladding material 608, a portion of the first light transmitting structure 612-1, a portion of the first light absorbing structure 610-1, and a portion of the second light transmitting structure 612-2 (e.g., because the cladding material 608, the first light transmitting structure 612-1, a portion of the first light absorbing structure 610-1, and a portion of the second light transmitting structure 612-2 are capable of transmitting light associated with the fourth wavelength range) to the second light absorbing structure 610-2 in the layer 606-1.

[0087] In some embodiments, each of the plurality of light absorbing structures 610 may be configured to generate heat 620 when a light beam having a wavelength within a wavelength range absorbed by the light absorbing structure 610 is incident on the light absorbing structure 610. The light absorbing structure 610 may provide heat 620 to a corresponding light transmitting structure 612 in the plurality of light transmitting structures 612. For example, when one or more light beams 616-1 are incident on a first light absorbing structure 610-1, the first light absorbing structure 610-1 may generate heat 620-1, and the first light absorbing structure 610-1 may provide heat 620-1 to the first light transmitting structure 612-1 (e.g., because the first light absorbing structure 610-1 is disposed on at least one surface of the first light transmitting structure 612-1). As another example, when one or more light beams 616-2 are incident on the second light absorbing structure 610-2, the second light absorbing structure 610-2 may generate heat 620-2, and the second light absorbing structure 610-2 may provide the heat 620-2 to the second light transmitting structure 612-2 (e.g., because the second light absorbing structure 610-2 is disposed adjacent to at least one surface of the second light transmitting structure 612-2).
