[0047] Figure 1 This is a cross-sectional schematic diagram of a photoelectric module 100 according to at least one embodiment of the present invention. Please refer to... Figure 1 The optoelectronic module 100 includes a filter structure 110, a transparent substrate 120, an optical fiber 130, an optoelectronic element 150, and a lens layer 140. The transparent substrate 120 covers the filter structure 110. The optical fiber 130 is inserted into the transparent substrate 120. The optoelectronic element 150 is disposed under the filter structure 110 and optically coupled to the optical fiber 130.

[0048] The optoelectronic module 100 may include at least one filter structure 110, at least one optical fiber 130, at least one optoelectronic element 150, and at least one lens layer 140. Specifically, in Figure 1 In the illustrated embodiment, the optoelectronic module 100 may include multiple filter structures 110, multiple optical fibers 130, multiple optoelectronic elements 150, and multiple lens layers 140. However, in other embodiments, the optoelectronic module 100 may include a single filter structure 110, a single optical fiber 130, a single optoelectronic element 150, and a single lens layer 140. Therefore, Figure 1 The number of each of the filter structure 110, optical fiber 130, optoelectronic element 150 and lens layer 140 is not limited.

[0049] Lens layer 140 and filter structure 110 are disposed between optical fiber 130 and photoelectric element 150. Lens layer 140 can be disposed between photoelectric element 150 and filter structure 110. In other words, filter structure 110 can be disposed between lens layer 140 and transparent substrate 120, wherein filter structure 110 can directly contact transparent substrate 120. Alternatively, lens layer 140 can also be disposed between filter structure 110 and transparent substrate 120, meaning that lens layer 140 can contact transparent substrate 120. In other words, filter structure 110 can be disposed between photoelectric element 150 and lens layer 140, meaning that filter structure 110 can directly contact photoelectric element 150.

[0050] Figure 2 yes Figure 1 A cross-sectional view of the filter structure 110 in the diagram. Please refer to [link / reference]. Figure 2 A transparent substrate 120 covers the filter structure 110. The filter structure 110 is designed based on the principle of a Fabry-Pérot interferometer. The filter structure 110 includes a first reflective layer 112, a second reflective layer 114, and a dielectric layer 116. The second reflective layer 114 is disposed below the first reflective layer 112. Both the first reflective layer 112 and the second reflective layer 114 each include a first dielectric layer and a second dielectric layer. The second dielectric layer may be disposed on the first dielectric layer. Alternatively, the second dielectric layer may be disposed between the first dielectric layer and the transparent substrate 120.

[0051] The first reflective layer 112 and the second reflective layer 114 can have more than one set of first and second dielectric layers, and are not limited to this. The first dielectric layer is made of silicon dioxide (SiO2), which means that the first dielectric layer is a low-refractive-index optical film layer, while the second dielectric layer is made of titanium dioxide (TiO2), which means that the second dielectric layer is a high-refractive-index optical film layer. The number of layers of the first reflective layer 112 and the second reflective layer 114 of the filter structure 110, that is, the number of sets of first and second dielectric layers, affects the emission spectral width at 50% of the peak intensity of the light wavelength, which is called the full width at half maximum (FWHM).

[0052] However, the more layers the filter structure 110 has—that is, the more groups of the first and second dielectric layers—the narrower the emission spectrum width at 50% of the peak intensity of the light wavelength. The design of the filter structure 110 can be evaluated by simulation programs, such as Macleod, ThinFilmView, or Filmetrics.

[0053] A dielectric layer 116 is disposed between the first reflective layer 112 and the second reflective layer 114. The first reflective layer 112 and the second reflective layer 114 are symmetrically stacked on both sides of the dielectric layer 116 with the dielectric layer 116 as the center. Alternatively, the first reflective layer 112 and the second reflective layer 114 may be asymmetrically stacked on both sides of the dielectric layer 116 with the dielectric layer 116 as the center.

[0054] exist Figure 1 In this structure, optical fiber 130 is used to transmit light, which has a wavelength, half of which is the optical thickness of the dielectric layer 116 of the filter structure 110. As described in previous paragraphs, the filter structure 110 is designed based on the principle of a Fabry-Pérot interferometer. The dielectric layer 116 can also be referred to as a cavity or space. The optical path difference between the reflected light from two adjacent beams in the dielectric layer 116 is expressed as ∆L = 2nlcosθ, where ∆L is the optical path difference, n is the refractive index, l is the thickness, nl is the optical thickness, and θ is the angle of incidence. However, the angle at which optical fiber 130 connects to the filter structure 110 is perpendicular, meaning the angle of incidence θ is 90°. Therefore, its optical path difference is expressed as ∆L = 2nl, which is half the wavelength of the optical thickness of the dielectric layer 116.

[0055] In this embodiment, the light transmitted by the optical fiber 130 can be visible light, such as green light (center wavelength of 525nm), or invisible light, such as infrared light (800nm ​​to 900nm).

[0056] The optoelectronic module 100 may further include a plurality of optical fibers 130 arranged in an array, a plurality of filter structures 110, and a plurality of lens layers 140, wherein the optical fibers 130 are inserted into the transparent substrate 120 and aligned with the filter structures 110 respectively. The filter structures 110 may be disposed in grooves in the transparent substrate 120. The filter structures 110 may also be connected to the ends of the optical fibers 130.

[0057] The optoelectronic element 150 in the optoelectronic module 100 can be a light-sensing element (not shown), such as a photodiode (PD), in which case the optoelectronic module 100 has an optical communication receiving function. Alternatively, the optoelectronic element 150 in the optoelectronic module 100 can be a light-emitting element (not shown), such as a light-emitting diode (LED), in which case the optoelectronic module 100 has an optical communication transmission function.

[0058] The optoelectronic module 100 also includes a barrier layer 160 surrounding the lens layers 140 and the filter structures 110. The barrier layer 160 is located on the transparent substrate 120 and between the optoelectronic element 150 and the transparent substrate 120. The barrier layer 160 helps to reduce lateral crosstalk between the multiple arrayed optoelectronic elements 150, between the lens layers 140, or between the filter structures 110 during light transmission.
