Description

Technical Field

[0001] The present invention provides an optical interconnection communication method and system, and specifically relates to the technical field of optical communications. Background Art

[0002] Optical interconnection is an optical communication method that uses optical fiber or other optical transmission media to exchange data among various components or subsystems in a computer. The principle is to achieve high-speed and efficient data transmission by converting electrical signals into optical signals and using the transmission of light in optical fibers and other media. The optical signals are then converted back into electrical signals at the receiving end. Modulating optical signals is an indispensable part of the optical transmission process. Microring modulation is an optical modulation technology based on microring resonators. A microring resonator is a ring-shaped optical microcavity. When light propagates in it, a specific resonant mode is formed due to the boundary conditions of the ring structure. The resonant characteristics of the microring can be changed by changing the refractive index, geometric dimensions of the microring, or introducing external control signals, thereby modulating the optical signal passing through the microring to achieve changes in the intensity, phase, frequency and other parameters of the optical signal. Summary of the invention

[0003] Microring modulators usually have a small size and can be integrated with other optical or electronic components on the same chip to improve the system's integration and performance. Compared with some traditional optical modulators, microring modulators can achieve higher modulation efficiency at lower driving power due to their resonance enhancement effect. They can achieve higher modulation rates and meet the data transmission speed requirements of applications such as high-speed optical communications and high-speed signal processing. They are easy to integrate with other photonic devices such as waveguides and detectors to form complex photonic functional modules, thus realizing an integrated on-chip optical interconnection system with multiple optical signal processing functions.

[0004] Existing commonly used micro-ring modulators, such as Figure 1 As shown, it is generally composed of a straight waveguide and a ring waveguide. The optical waveguide length of the ring waveguide is the same as that of the straight waveguide. Its special ring structure will cause interference between the light in the straight waveguide when propagating in the ring waveguide, thereby causing the light field in the microring (MR) modulator to oscillate. By applying different voltages to the electrodes, the refractive index of the microring can be modulated, thereby controlling the propagation speed and interference of light in the microring, and realizing the modulation of the optical signal. However, the optical bandwidth of the microring modulator is narrow. In addition, it is more sensitive to temperature changes, because temperature changes will cause changes in parameters such as the refractive index of the material and the size of the microring, thereby affecting the propagation characteristics and resonance conditions of the optical signal in the microring. In practical applications, the microring modulator often brings about temperature changes during modulation due to its power, affecting the performance of the microring modulator. Therefore, it is particularly important to control or compensate for the temperature during its operation.

[0005] The present invention provides an optical interconnection communication method and system, comprising a plurality of laser array modules, optical waveguide modules, optical modulation modules, optical receiving conversion modules, and a processor connected in sequence, wherein the laser array module comprises a plurality of laser emission sources of different single wavelengths and their corresponding electro-optical conversion modules, and the optical waveguide module comprises a plurality of parallel waveguide optical paths, each waveguide optical path is provided with a first beam splitter and a second beam splitter, light enters the first beam splitter from an input port, and then is divided into two paths of light, respectively enters two parallel optical waveguides, and after modulation, is output through the merging action of the second beam splitter. A composite micro-ring modulator is provided between the two parallel optical waveguides, and the composite micro-ring modulator constitutes an optical modulation module, and the optical receiving conversion module comprises a plurality of laser receivers and their corresponding photoelectric conversion modules, and the laser array module, the optical waveguide module, the optical modulation module, the optical receiving conversion module, and the processing module are integrated on a substrate, wherein the laser array module, the optical waveguide module, the optical modulation module, and the optical receiving conversion module are all integrated on a silicon substrate chip, and the silicon substrate chip is integrated on the substrate.

[0006] The specific structure diagram of the coupling modulation of the optical modulation module and two parallel optical waveguides is shown. The optical modulation module is composed of four identical microrings, namely, microring 1, microring 2, microring 3 and microring 4. The two parallel optical waveguides are composed of linear waveguide 1 and linear waveguide 2. There is a coupling spacing between microring 1 and linear waveguide 1, and there is a coupling spacing between microring 2 and linear waveguide 2. In addition, as shown in the figure, there are switchable coupling regions 1, 2, 3, 4 and 5 between microring 1 and microring 2, between microring 1 and microring 3, between microring 3 and microring 2, between microring 2 and microring 4, and between microring 4 and microring 1. Microring 1 and microring 2 are optically coupled to the upper linear waveguide 1 and to the lower linear waveguide 2 in an upper-lower symmetric manner; microring 3 and microring 4 are optically coupled to microring 1 and microring 2 in a left-right symmetric manner at coupling regions 2, 3, 4 and 5, respectively. As shown in FIG. 1 , a light beam T with a certain wavelength emitted by a laser emission source is divided into two identical light beams t1 and t2 by a beam splitter. Taking the second light beam t2 passing through the linear waveguide 2 as an example, when the second light beam t2 passes through the coupling gap between the micro-ring 1 and the linear waveguide 2, the first part of the second light beam t2 passing through the linear waveguide 2 after passing through the micro-ring 1 becomes a first straight-through signal, which is marked as t in the figure. 21 . The first direct signal t 21 is the modulated signal sent to the coupler. The second part of the second light beam t enters the micro-ring to form the first ring signal t 22 , the first ring signal t 22After passing through the right semicircle of microring 1 for modulation, when the first optical signal passes through the coupling zone 1 between microring 1 and microring 2, a part of the first optical signal continues to be modulated along microring 1, which is marked as the second optical signal in the figure, and another part of the first optical signal enters microring 2 for modulation, which is marked as the third optical signal in the figure. After the second optical signal passes through the optical oscillation in microring 1 for one cycle, it will meet the light in linear waveguide 2 again and enter linear waveguide 2 to achieve modulation. After the third optical signal passes through the optical oscillation in the right semicircle path of microring 1 and the left semicircle path of microring 2 for one cycle, it will meet the light in linear waveguide 1 again and enter linear waveguide 1 to achieve modulation. The modulation process of the first light beam t1 is the same as that of the second light beam t2, and finally the third optical signal and the second optical signal are respectively generated and meet the light beam in the linear waveguide to achieve modulation. Through the design of the above two microrings, the modulation of one beam T is achieved. Compared with the modulator of a single microring in the prior art, the power consumption of a single microring when working is greatly reduced, and the influence of ambient temperature on the microring modulator is reduced. The materials of linear waveguides and micro-ring waveguides include silicon, silicon nitride, lithium niobate or tantalum oxide.

[0007] The optical modulation module is composed of four micro-rings, and micro-ring three and micro-ring four are further symmetrically arranged. The centers of micro-ring three and micro-ring four are both located on the extension line of the middle axis of the coupling area between micro-ring one and micro-ring two. Coupling area two and coupling area three are distributed between micro-ring three and micro-ring one and micro-ring two, and coupling area four and coupling area five are distributed between micro-ring four and micro-ring one and micro-ring two. Micro-ring three and micro-ring four are symmetrically arranged on the left and right. Coupling area two and coupling area three between micro-ring three and micro-ring one and micro-ring two can be controlled to switch, and coupling area four and coupling area five between micro-ring four and micro-ring one and micro-ring two can be controlled to switch. The specific switch control is that the optical signal passing through micro-ring one can choose whether to enter micro-ring three or micro-ring four coupled with it. Specifically, the passage of the light beam in the coupling area can be realized by setting a movable micro-reflector in the coupling area or applying an electrical signal to control the lens set in the coupling area.

[0008] The coupling control of micro-ring 3 and micro-ring 1 is used as an example to illustrate that, on the basis of the simultaneous modulation of light beams t1 and t2 by micro-ring 1 and micro-ring 2, micro-ring 3 and micro-ring 4 coupled with micro-ring 1 are additionally provided. When micro-ring 3 is coupled with micro-ring 1, the first ring signal t transmitted counterclockwise through micro-ring 1 22 One part enters micro-ring 1 and micro-ring 2 for modulation as described above, and the other part can be controlled to enter micro-ring 3 for modulation. As shown in the figure, the first ring signal t entering micro-ring 1 22When passing through coupling zone two, a part continues to be transmitted counterclockwise along micro-ring one, and a part enters micro-ring three and transmits in micro-ring three in a clockwise direction for one circle before re-passing through coupling zone two and re-entering micro-ring one. This operation realizes the modulation of the second light beam t by three micro-rings: micro-ring one, micro-ring two, and micro-ring three, further reducing the power consumption of a single micro-ring; similarly, micro-ring four can also be coupled to micro-ring one to realize four micro-rings (micro-ring one, micro-ring two, micro-ring three, and micro-ring four) combined with a linear waveguide to modulate the second light beam t2, while the first light beam t1 is modulated by micro-ring one and micro-ring two combined with a linear waveguide; further, similar to the above, micro-ring three and micro-ring four can be controllably coupled to micro-ring two to realize the modulation of the first light beam t1 by the four micro-rings.

[0009] Further, the controllable coupling between micro-ring 3 and micro-ring 1 is taken as an example to introduce the coupling control between the two. Similarly, the controllable coupling between micro-ring 3 and micro-ring 2, between micro-ring 4 and micro-ring 1, and between micro-ring 4 and micro-ring 2 are the same. Specifically, a movable micro-reflector is provided in the coupling region 2 between micro-ring 3 and micro-ring 1. When the micro-reflector moves to the coupling region 2 between micro-ring 3 and micro-ring 1, the first ring signal t 22 All continue to transmit along micro-ring 1, without entering micro-ring 3. When the micro-reflector moves out of the coupling zone 2 between micro-ring 3 and micro-ring 1, the first ring signal t 22 Part of it continues to transmit along micro-ring 1, and the other part enters micro-ring 3, thus realizing the first ring signal t 22 Controllable selection of the light path; in addition, the above-mentioned controllable light path selection can be achieved by controlling the transmittance of the lens in the coupling area through an electrical signal to determine whether the light passes through the coupling area.

[0010] Furthermore, taking micro-ring three and micro-ring four cooperating with coupled micro-ring one to modulate the first light beam as an example, a modulation method based on a composite micro-ring modulator is proposed, wherein micro-ring three and micro-ring four are intermittently operated by periodically coupling or disconnecting with micro-ring one at intervals in time, so that micro-ring three and micro-ring four can rest or work intermittently, thereby further reducing the power consumption of micro-ring three and micro-ring four; specifically, as shown in the figure, in the time period when the y value is positive, micro-ring three is coupled with micro-ring one, at which time, a part of the optical signal passing through micro-ring one simultaneously enters micro-ring three for modulation, micro-ring four is coupled with micro-ring one, and the optical signal passing through micro-ring one does not enter micro-ring four for modulation; in the time period when the y value is negative, micro-ring three is not coupled with micro-ring one, at which time, the optical signal passing through micro-ring one does not enter micro-ring three for modulation, and a part of the optical signal passing through micro-ring one simultaneously enters micro-ring four for modulation, so that micro-ring three and micro-ring four intermittently participate in the modulation of the optical signal, and both get a rest, thereby reducing the power consumption of each micro-ring and greatly reducing the influence of temperature on micro-ring modulation.

[0019] Reference Figure 2 The present invention provides a micro-ring-based optical interconnection communication method and system, comprising a plurality of laser array modules 1, an optical waveguide module 2, an optical modulation module 3, an optical receiving conversion module 4, and a processor 5 connected in sequence, wherein the laser array module 1 comprises a plurality of laser emission sources 11 of different single wavelengths and their corresponding electro-optical conversion modules 12, the optical waveguide module 2 comprises a plurality of parallel waveguide optical paths, each waveguide optical path is provided with a first beam splitter and a second beam splitter, light enters the first beam splitter from an input port, and then is divided into two paths of light, respectively entering two parallel optical waveguides, and after being modulated, is output through the combining action of the second beam splitter. A composite micro-ring modulator is arranged between two parallel optical waveguides, and the composite micro-ring modulator constitutes an optical modulation module. The optical receiving conversion module 4 includes multiple laser receivers 41 and their corresponding photoelectric conversion modules 42. The laser array module 1, the optical waveguide module 2, the optical modulation module 3, the optical receiving conversion module 4 and the processing module 5 are integrated on the substrate 6, wherein the laser array module 1, the optical waveguide module 2, the optical modulation module 3 and the optical receiving conversion module 4 are all integrated on a silicon substrate chip, and the silicon substrate chip is integrated on the substrate 6.

[0020] Reference Figure 3 As shown, it is a specific structural diagram of the coupling modulation of the optical modulation module 3 and the two parallel optical waveguides. The optical modulation module 3 is composed of four identical microrings, microring 1 31, microring 2 32, microring 3 33, and microring 4 34. The two parallel optical waveguides are composed of a straight waveguide 1 21 and a straight waveguide 2 22. There is a coupling spacing between the microring 1 31 and the straight waveguide 1 21, and there is a coupling spacing between the microring 2 32 and the straight waveguide 2 22. In addition, as Figure 3As shown, there are switchable coupling regions 1 312, 2 313, 323, 4 324, and 5 314 between microring 1 31 and microring 2 32, between microring 1 31 and microring 3 33, between microring 3 33 and microring 2 32, between microring 2 32 and microring 4 34, and between microring 4 34 and microring 1 31. Microring 1 31 and microring 2 32 are optically coupled to upper linear waveguide 1 21 and to lower linear waveguide 2 22 in an up-down symmetrical manner; microring 3 33 and microring 4 34 are optically coupled to microring 1 31 and microring 2 32 in coupling regions 2 313, 323, 4 324, and 5 314 in a left-right symmetrical manner.

[0021] Reference Figure 3-4 As shown in the figure, an example of modulation by two microrings, microring 1 31 and microring 2 32, is given. A light beam T with a certain wavelength emitted by a laser emission source 11 is divided into two identical light beams t1 and t2 by a beam splitter. Figure 4 Taking the second light beam t2 passing through the linear waveguide 22 as an example, when the second light beam t2 passes through the coupling gap between the micro-ring 1 31 and the linear waveguide 22, the first part of the second light beam t2 passing through the linear waveguide 22 after passing through the micro-ring 1 31 becomes the first straight-through signal. Figure 4 is marked as t 21 . The first direct signal t 21 The second part of the second light beam t2 enters the micro-ring 1 31 to form the first ring signal t 22 , the first ring signal t 22 The right semicircle of the micro-ring 31 is modulated. Figure 4 In FIG. 3 , the first optical signal 311 is marked as the first optical signal 311. When the first optical signal 311 passes through the coupling region 1 312 between the micro-ring 1 31 and the micro-ring 2 32, a part of the first optical signal 311 continues to be modulated along the micro-ring 1 31. Figure 4 The other part of the first optical signal 311 enters the micro-ring 2 32 for modulation. Figure 4The third optical signal 322 is marked in the figure. After the second optical signal 311' passes through the optical oscillation in the micro-ring 1 31 for one cycle, it will meet the light in the linear waveguide 2 22 again and enter the linear waveguide 2 22 to achieve modulation. After the third optical signal 322 passes through the optical oscillation in the right semicircular path of the micro-ring 1 31 and the left semicircular path of the micro-ring 2 32 for one cycle, it will meet the light in the linear waveguide 1 21 again and enter the linear waveguide 1 21 to achieve modulation. The modulation process of the first light beam t1 is the same as that of the second light beam t2, and finally the third optical signal 322 and the second optical signal 311' are generated respectively, and meet the light beam in the linear waveguide to achieve modulation; that is, the optical signal in the upper linear waveguide 1 21 is compound modulated through the entire circular optical path of the micro-ring 2 32 and the left semicircular optical path of the micro-ring 1 31, and the optical signal in the lower linear waveguide 1 22 is compounded through the entire circular optical path of the micro-ring 1 31 and the left semicircular optical path of the micro-ring 2 32. Through the design of the above two micro-rings, the modulation of a beam T is achieved. Compared with the existing technology (such as Figure 1 ) of a single micro-ring modulator, which greatly reduces the power consumption of a single micro-ring when working and reduces the influence of ambient temperature on the micro-ring modulator. The materials of the linear waveguide and micro-ring waveguide include: silicon, silicon nitride, lithium niobate or tantalum oxide.

[0022] Continue to refer to the attached Figure 3-4 Further, the optical modulation module 3 is composed of four micro-rings, and the micro-ring three 33 and the micro-ring four 34 are further symmetrically arranged. The centers of the micro-ring three 33 and the micro-ring four 34 are both located on the extension line of the middle axis of the coupling area between the micro-ring one 31 and the micro-ring two 32. There are coupling areas two 313 and three 323 between the micro-ring three 33 and the micro-ring one 31 and the micro-ring two 32. There are coupling areas four 324 and five 314 between the micro-ring four 34 and the micro-ring one 31 and the micro-ring two 32. The micro-ring three 33 and the micro-ring four 34 are symmetrically arranged left and right. The coupling zone two 313 and coupling zone three 323 between ring three 33 and micro-ring one 31 and micro-ring two 32 can be controlled to switch, and the coupling zone four 324 and coupling zone five 314 between micro-ring four 34 and micro-ring one 31 and micro-ring two 32 can be controlled to switch. The specific switch control is that the optical signal passing through micro-ring one 31 can choose whether to enter micro-ring three 33 or micro-ring four 34 coupled thereto. Specifically, a movable micro-reflector can be set in the coupling zone or an electrical signal can be applied to control the lens set in the coupling zone to realize whether the light beam in the coupling zone passes through.

[0023] The coupling control of micro-ring 33 and micro-ring 1 31 is used as an example for explanation. On the basis of the simultaneous modulation of light beams t1 and t2 by micro-ring 1 31 and micro-ring 2 32, micro-ring 33 and micro-ring 4 34 coupled with micro-ring 1 31 are additionally provided. When micro-ring 33 is coupled with micro-ring 1 31, the first ring signal t transmitted counterclockwise through micro-ring 1 31 is 22A portion enters micro-ring 1 31 and micro-ring 2 32 for modulation as described above, and another portion can be controlled to enter micro-ring 3 33 for modulation, such as Figure 4 As shown, the first ring signal t entering micro-ring 1 22 When passing through coupling zone two 313, a part continues to be transmitted counterclockwise along micro-ring one 31, and a part enters micro-ring three 33 and transmits in micro-ring three 33 in a clockwise direction for one circle before re-passing through coupling zone two 313 and re-entering micro-ring one 31. This operation realizes the modulation of the second light beam t2 by three micro-rings: micro-ring one 31, micro-ring two 32, micro-ring three 33, and micro-ring four 34, further reducing the power consumption of a single micro-ring; similarly, micro-ring four 34 can also be coupled to micro-ring one 31 to realize four micro-rings (micro-ring one 31, micro-ring two 32, micro-ring three 33, and micro-ring four 34) combined with a straight waveguide to modulate the second light beam t2, while the first light beam t1 is modulated through micro-ring one 31 and micro-ring two 32 combined with a straight waveguide; further, similar to the above, micro-ring three 33 and micro-ring four 34 can be controllably coupled to micro-ring two 32 to realize the modulation of the first light beam t1 by the four micro-rings.

[0024] Further, the controllable coupling between micro-ring 3 33 and micro-ring 1 31 is taken as an example to introduce the coupling control between the two. Similarly, the controllable coupling between micro-ring 3 33 and micro-ring 2 32, between micro-ring 4 34 and micro-ring 1 31, and between micro-ring 4 34 and micro-ring 2 32 are the same. Specifically, a movable micro-reflector is provided in the coupling region 2 313 between micro-ring 3 33 and micro-ring 1 31. When the micro-reflector moves to the coupling region 2 313 between micro-ring 3 33 and micro-ring 1 31, the first ring signal t 22 All continue to transmit along the micro-ring 1 31 without entering the micro-ring 3 33. When the micro-reflector moves out of the coupling region 2 313 between the micro-ring 3 33 and the micro-ring 1 31, the first ring signal t 22 A part of the signal continues to be transmitted along the micro-ring 1 31, and the other part enters the micro-ring 3 33, thereby realizing the first ring signal t 22 Controllable selection of the light path; in addition, the above-mentioned controllable light path selection can be achieved by controlling the transmittance of the lens in the coupling area through an electrical signal to determine whether the light passes through the coupling area.

[0025] Further, taking the modulation of the first light beam by micro-ring three 33 and micro-ring four 34 in cooperation with the coupled micro-ring one 31 as an example, a modulation method based on a composite micro-ring modulator is proposed, wherein the processor 6 controls the micro-ring three 33 and micro-ring four 34 to periodically couple or disconnect with the micro-ring one 31 at intervals in time to realize the intermittent operation of micro-ring three 33 and micro-ring four 34, so that micro-ring three 33 and micro-ring four 34 can rest or work intermittently, thereby further reducing the power consumption of micro-ring three 33 and micro-ring four 34; specifically, as Figure 5As shown, during the time period when the y value is a positive value, micro-ring three 33 is coupled with micro-ring one 31. At this time, a part of the optical signal passing through micro-ring one 31 simultaneously enters micro-ring three 33 for modulation, and micro-ring four 34 is coupled with micro-ring one 31, and the optical signal passing through micro-ring one 31 does not enter micro-ring four 34 for modulation; during the time period when the y value is a negative value, micro-ring three 33 is not coupled with micro-ring one 31. At this time, the optical signal passing through micro-ring one 31 does not enter micro-ring three 33 for modulation, and a part of the optical signal passing through micro-ring one 31 simultaneously enters micro-ring four 34 for modulation. In this way, micro-ring three 33 and micro-ring four 34 intermittently participate in the modulation of the optical signal, and both get a rest, which reduces the power consumption of each micro-ring and greatly reduces the influence of temperature on micro-ring modulation.
