[0020] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0021] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Common optical communication methods rely on radio waves such as centimeter waves and millimeter waves for optical communication, and use semiconductor photodetectors at the optical signal receiving end to receive the optical signal. However, the sensitivity of traditional semiconductor photodetectors drops significantly to short-wavelength light. Although they perform well in the infrared band (1300 to 1600 nm), their performance deteriorates drastically in the visible light range (400 to 700 nm). This means that methods to increase speed by reducing device size are difficult to implement in the visible light domain. Due to these physical limitations, high-speed communication and interconnection technologies for short-wavelength light have stagnated for a long time. Even more serious is the fact that semiconductor diode detectors rely on single-crystal substrates, which severely limits their system integration flexibility. From an engineering perspective, this hinders the development of compact optical communication and interconnection technologies such as co-packaged optics, which is key to the rise of photoelectric conversion technology. Therefore, a new method for realizing optical communication is urgently needed.

[0023] Therefore, based on the shortcomings of the above optical communication methods, the optical communication method of this application is proposed. The solution of the embodiments of this application is: to obtain optical communication data by processing the photoelectric conversion signal of a spin photodetector, and then to realize the optical communication method based on the optical communication data. That is, optical communication can be realized using a spin photodetector, avoiding the phenomenon that semiconductor photodetectors limit their own optical communication effect (for example, semiconductor detectors need to rely on a single crystal substrate, which severely limits their optical communication integration flexibility, and semiconductor detectors need to reduce the size of the device to increase speed, but this will sacrifice sensitivity). In other words, this optical communication method can realize optical communication using a spin photodetector, thus providing a way to realize optical communication using a spin photodetector.

[0024] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or a device capable of performing the above functions, such as a vehicle control terminal. The following description uses a vehicle control terminal as an example to illustrate this embodiment and the subsequent embodiments.

[0025] Based on this, embodiments of this application provide an optical communication method, referring to... Figure 1 , Figure 1 This is a schematic flowchart of the first embodiment of the optical communication method of this application at the optical receiver.

[0026] Reference Figure 1 This application provides an optical communication method. In a first embodiment of the optical communication method, the optical communication method is applied to an optical receiver, which includes a spin photodetector. The optical communication method includes: Step S10: Acquire the optical signal and perform photoelectric conversion on the optical signal based on the spin photodetector to obtain the photoelectric conversion signal, wherein the optical signal includes the optical signal emitted by the optical transmitter in the optical transmitter under the control of the target driving signal; In this embodiment, the optical communication method is applied to an optical receiver including an MTJ PD (Magnetic Tunnel Junction Photodetector). The spin photodetector can be used to collect the optical signal emitted by the optical transmitter, then perform photoelectric conversion to obtain an electrical signal, thus completing the optical signal reception. The application of the spin photodetector enables optical communication through a novel optical reception method. Furthermore, compared to traditional semiconductor photodetectors, spin photodetectors have a faster response speed and can detect a wider wavelength range of light, including visible light, thereby significantly improving the optical communication effect. For example, the spin photodetector can be composed of a transparent electrode, a free layer, a barrier layer (insulator), a pinned layer, and a metal electrode in sequence. When the optical signal irradiates the transparent electrode, a current is formed between the transparent electrode and the metal electrode based on rotating electron technology, thereby achieving photoelectric conversion. The principle is that when the light pulse passes through the top electrode and irradiates the free layer, the photon energy is rapidly absorbed and converted into heat from the lattice and electron spin system, causing the free layer temperature to rise sharply within picoseconds. This instantaneous temperature rise significantly reduces the magnetic anisotropy of the free layer, causing a transient deflection or precession of its magnetization vector. The relative angle (θ) between the magnetization directions of the free layer and the reference layer thus changes. According to the magnetoresistance effect of the magnetic tunnel junction, the resistance R of the spin photodetector satisfies the relationship: R = R0 / (1 + TMR* cosθ), where R0 is the antiparallel resistance and TMR is the tunneling magnetoresistance ratio. Therefore, even a small change in magnetization angle θ can be converted into a detectable device resistance signal R. This process is completely different from the mechanism in semiconductor photodiodes where electron-hole pairs are generated and then migrate under the influence of an electric field, thus avoiding the limitations imposed by carrier drift velocity and diffusion capacitance on the response speed, thereby achieving a high-speed response. The electrical signal from the spin photodetector can then be processed to obtain the signal required for communication, thus completing optical communication.

[0027] Step S20: Determine optical communication data based on photoelectric conversion signal, and realize optical communication based on optical communication data.

[0028] In this embodiment, after determining the photoelectric conversion signal, the photoelectric conversion signal is processed to obtain optical communication data, and then the optical communication process can be completed based on the optical communication data. For example, the magnitude of the electrical signal after photoelectric conversion by the spin photodetector can be directly determined to be a high-level or low-level signal, and then optical communication can be performed based on the high-level or low-level signal. Furthermore, data transmission can also be achieved by transmitting a high-low level segment of the optical signal. For example, if the final optical communication data is 000011, it indicates that the optical communication is the number 3. Of course, the number 3 can also be used to represent other communication data, such as the data represented in a lookup table. Thus, a spin photodetector can be used to implement optical communication, and a new optical communication receiver design can be implemented to ensure the optical communication effect.

[0029] In this embodiment, an optical communication method is provided, applied to an optical receiver. The optical receiver includes a spin photodetector, which acquires optical signals and performs photoelectric conversion on the optical signals based on the spin photodetector to obtain a photoelectric conversion signal. The optical signals include optical signals emitted by an optical transmitter in an optical transmitter under the control of a target driving signal. Optical communication data is determined based on the photoelectric conversion signal, and optical communication is realized based on the optical communication data. This optical communication method obtains optical communication data by processing the photoelectric conversion signal of the spin photodetector, and then realizes optical communication based on the optical communication data. That is, optical communication can be realized using a spin photodetector, avoiding the phenomenon that semiconductor photodetectors limit their own optical communication effect (for example, semiconductor detectors need to rely on single-crystal substrates, which severely limits their optical communication integration flexibility, and semiconductor detectors need to reduce device size to increase speed, but this sacrifices sensitivity). In other words, this optical communication method can realize optical communication using a spin photodetector, thus providing a way to realize optical communication using a spin photodetector.

[0030] Furthermore, based on the first embodiment of this application described above, a second embodiment of the optical communication method of this application is proposed. In this embodiment, step S20, the step of determining optical communication data based on the photoelectric conversion signal, includes: Step S21: Determine the electrical parameter values ​​corresponding to the photoelectric conversion signal; Step S22: When the electrical parameter value is a preset high-level parameter threshold, determine that the optical communication data is at a high level; Step S23: When the electrical parameter value is a preset low-level parameter threshold, determine that the optical communication data is at a low level.

[0031] In this embodiment, determining the optical communication data mainly involves determining whether the optical signal received by the spin photodetector corresponds to a high-level or low-level electrical signal. This is done by determining the electrical parameter value corresponding to the photoelectric conversion signal. For example, if the induced current value generated by the spin photodetector is A-1, then the electrical parameter value corresponding to the photoelectric conversion signal is determined to be A-1. Furthermore, it is determined whether A-1 falls within a preset high-level parameter threshold or a preset low-level parameter threshold. For example, assuming a preset low-level parameter threshold of 0-A and a preset high-level parameter threshold of A-2A are defined in advance, the electrical parameter value can be determined to be the preset low-level parameter threshold, i.e., the optical communication data is determined to be low-level. Further, the spin photodetector can also directly receive the optical signal and store the corresponding high / low level data. For example, when the light pulse irradiates the MTJPD, the magnetization direction of its free layer is changed (flipped or set) through photothermal effect or phototorque effect. After the light pulse ends, the magnetization direction of the free layer will stabilize in the new state. Since the MTJ is based on ferromagnetic material, this magnetic state is non-volatile, meaning the information is still preserved after power is cut off. At this point, the information has been transferred from the optical domain to the magnetic domain and stored. For example, a dynamic comparator can be used to detect photoelectric conversion signals. The photoelectric conversion signals are compared in the dynamic comparator, and the comparison result is used as optical communication data. That is, the comparison value of the dynamic comparator is set to the boundary between a preset high-level parameter threshold and a preset low-level parameter threshold. For example, when the comparator is a current comparison circuit, its positive or negative input terminal is electrically connected to one electrode (e.g., the top electrode) of the spin photodetector. When a light signal shines on the spin photodetector, its resistance changes. Applying a constant bias voltage Vbias across the spin photodetector will change the current difference across it (ΔI = Vbias / ΔR). Alternatively, the comparator can be a voltage comparison circuit. In this case, applying a constant bias current Ibias across the spin photodetector will change the voltage difference across it as the resistance of the spin photodetector changes (ΔV = Ibias * ΔR). The comparator has a preset reference voltage Vref, which is used to compare the analog voltage change signal of the spin photodetector with the preset reference voltage Vref. The comparator's output changes when the input analog voltage exceeds the reference voltage Vref threshold, thus converting the analog light intensity signal into a digital "0" or "1" signal output. Furthermore, since the principle of a spin photodetector is based on changes in induced current caused by light signals, changes in voltage or other electrical parameters caused by the induced current can also be detected. These changes in electrical parameters can then be used to determine the optical communication data, enabling optical communication based on the spin photodetector.

[0032] In another embodiment, the optical receiver includes a first spin photodetector for signal reception and a second spin photodetector for signal processing, wherein the second spin photodetector is in a blocked state, and the optical communication method further includes: Step S201: Obtain the noise electrical signal of the second spin photodetector, update the photoelectric conversion signal based on the noise electrical signal, and perform the step of determining optical communication data based on the photoelectric conversion signal based on the updated photoelectric conversion signal.

[0033] In this embodiment, the optical receiver includes a first spin photodetector for signal reception and a second spin photodetector for signal processing. The first spin photodetector receives the optical signal emitted from the optical transmitter and processes it to obtain the optical communication data required for optical communication. Simultaneously, the second spin photodetector is shielded, for example, by using a black shielding film, effectively collecting ambient noise. The noise signal from the second spin photodetector is then acquired. This noise signal is the electrical signal generated after the ambient light undergoes photoelectric conversion. The photoelectric conversion signal can be updated based on the noise signal, for example, by directly subtracting the noise signal from the photoelectric conversion signal. Based on the photoelectric conversion signal after subtracting the noise signal, the step of determining the optical communication data based on the photoelectric conversion signal is performed to suppress the influence of ambient noise on the entire optical communication process, thereby ensuring the accuracy of the optical communication. For example, updating the photoelectric conversion signal based on the noise electrical signal can be handled differently in different situations. For instance, when the photoelectric conversion signal is large, the noise electrical signal can be ignored. However, when the noise electrical signal exceeds a certain threshold, the photoelectric conversion signal needs to be updated. Conversely, when the noise electrical signal is small, the photoelectric conversion signal does not need to be updated. This can greatly improve the intelligence of optical communication and the accuracy of use in different scenarios.

[0034] Furthermore, based on the first and / or second embodiments described above, applied to an optical receiver including a spin photodetector, a first embodiment of the optical communication method of this application applied to an optical transmitter is proposed. The optical transmitter includes an optical transmitter, as shown in the reference. Figure 2 , Figure 2 This is a schematic flowchart of the first embodiment of the optical communication method of this application at the optical transmitter: Step S30: Obtain the target driving signal; In this embodiment, the initial driving signal needs to be processed during optical communication to obtain the target driving signal. The target driving signal can then be used to control the optical transmitter, causing it to transmit light signals to a spin photodetector, thus completing the entire optical communication process based on the spin photodetector. The initial driving signal refers to the signal that drives the optical transmitter to emit light, while the target driving signal is the processed initial driving signal, generally a driving signal designed to prevent interference between adjacent signals. The optical transmitter can be a MicroLED (Micro Light-Emitting Diode), but other light-emitting devices are also possible and not limited here. Because a spin photodetector is used at the optical receiver to avoid semiconductor defects, a new optical communication method can be provided.

[0035] Step S40: Drive the optical transmitter based on the target driving signal to make the optical transmitter emit an optical signal. The optical receiver performs photoelectric conversion on the optical signal based on a spin photodetector to obtain a photoelectric conversion signal, and determines the optical communication data based on the photoelectric conversion signal. In this embodiment, after the target driving signal is determined, the optical transmitter is driven based on the target driving signal to emit an electro-optical conversion signal. The electro-optical conversion signal includes an optical signal emitted by the optical transmitter under the control of the driving signal. At this time, the optical signal can be transmitted to the spin photodetector through optical transmission devices, etc. The spin photodetector performs photoelectric conversion on the optical signal to obtain an electrical signal, and then processes the electrical signal to obtain the final optical communication data to be communicated, so as to complete the optical communication based on the spin photodetector.

[0036] In this embodiment, an optical communication method is provided, applied to an optical emitting end including an optical transmitter, to acquire a target driving signal; the optical transmitter is driven based on the target driving signal to emit an optical signal, wherein the optical receiving end performs photoelectric conversion on the optical signal based on a spin photodetector to obtain a photoelectric conversion signal, and determines optical communication data based on the photoelectric conversion signal. Furthermore, at the optical receiving end, optical communication data is determined based on the photoelectric conversion signal to achieve optical communication. This optical communication method processes the photoelectric conversion signal of the spin photodetector to obtain optical communication data, and then achieves optical communication based on the optical communication data. That is, optical communication can be achieved using a spin photodetector, avoiding the phenomenon that semiconductor photodetectors limit their optical communication performance (for example, semiconductor detectors rely on single-crystal substrates, which severely limits their optical communication integration flexibility, and increasing the speed of semiconductor detectors requires reducing device size, but at the cost of sensitivity). In other words, this optical communication method can achieve optical communication using a spin photodetector, thus providing a way to achieve optical communication using a spin photodetector.

[0037] In one embodiment, the step of acquiring the target driving signal includes: Step S31: The initial driving signal is processed based on a preset signal processing method to obtain the target driving signal, wherein the preset signal processing method includes signal equalization and enhancement.

[0038] In this embodiment, to avoid the influence of adjacent optical signal transmission, the initial driving signal can be processed based on a preset signal processing method to obtain the target driving signal. This preset signal processing method includes signal equalization and enhancement, such as using an emphasis converter / forward equalizer to equalize and enhance the high-frequency range of the signal from the micro-LED driver, thereby avoiding the influence of adjacent optical signal transmission and ensuring the accuracy of signal transmission. For example, if the initial driving signal is used directly for control, the results from the spin photodetector will show a long trailing effect, affecting the transmission of the next signal. By equalizing and enhancing the high-frequency range of the signal from the micro-LED driver, the trailing problem can be eliminated, ensuring the accuracy of signal transmission.

[0039] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the optical communication method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0040] This application also provides an optical communication system, as shown in the reference. Figure 6 The optical communication system utilizes the aforementioned optical communication method. The optical communication system includes an optical transmitter and an optical receiver. The optical receiver includes a spin photodetector, and the optical transmitter includes an optical transmitter. The optical transmitter 60 is used to acquire the target driving signal; and to drive the optical transmitter based on the target driving signal so that the optical transmitter emits an optical signal. The optical receiver 50 is used to acquire optical signals and perform photoelectric conversion on the optical signals based on a spin photodetector to obtain photoelectric conversion signals; optical communication data is determined based on the photoelectric conversion signals to realize optical communication.

[0041] The optical communication method system provided in this application, employing the optical communication method described in the above embodiments, can provide a novel optical communication method to realize optical communication. Compared with the prior art, the beneficial effects of the optical communication method system provided in this application are the same as those of the optical communication method provided in the above embodiments, and other technical features of the optical communication method system are the same as those disclosed in the methods of the above embodiments, and will not be repeated here.

[0042] In one embodiment, the optical communication system further includes an optical transmission device 70, and the optical transmitter 60 includes: Transmitting optical block 61 and transmitting controller; The light emitter 62 has its emitting end 622 integrated into the first end of the light transmission device 70 via the emitting optical block 61. The flexible circuit board 63 is used for transmitting light. The first end of the flexible circuit board 63 is connected to the control end of the light emitter 62, and the second end of the flexible circuit board 63 is connected to the transmitting controller.

[0043] In this embodiment, the optical communication system further includes an optical transmission device 70, which connects the optical transmitter 60 and the optical receiver 50 to achieve optical communication between them. In this case, the transmitting end 622 of the optical transmitter 62 is integrated into the first end of the optical transmission device 70 via a transmitting optics block 61. The optical transmission device 70 can be a waveguide or optical fiber, or other optical communication devices. For example, see [reference needed]. Figure 3 , Figure 3 This is a schematic diagram of the optical transmitter in the optical communication method of this application. In this case, the transmitting end 622 of the optical transmitter 62 is refracted by the transmitting optical block 61 and transmits the optical signal to the first end of the optical transmission device 70. The transmitting optical block 61 is essentially designed as a refractive component to refract the light from the transmitting end 622 of the optical transmitter 62 into the first end of the optical transmission device 70, thereby avoiding interference between different optical signals. In another embodiment, see... Figure 4 , Figure 4This is another schematic diagram of the optical transmitter in the optical communication method of this application. In this case, the transmitting end 622 of the optical transmitter 62 is reflected by the transmitting optical block 61 and then transmits the optical signal to the first end of the optical transmission device 70. The transmitting optical block 61 is equivalent to a reflective component designed to refract the light from the transmitting end 622 of the optical transmitter 62 into the first end of the optical transmission device 70. The reflective and refractive components can be selected according to actual conditions and are not limited here. Furthermore, the first end of the transmitting flexible circuit board 63 is connected to the control end of the optical transmitter 62, and the second end of the transmitting flexible circuit board 63 is connected to the transmitting controller. Thus, the driving signal processing can be completed based on the transmitting controller to ensure the accuracy of optical signal transmission and communication.

[0044] In one embodiment, the optical receiver 50 includes: Receive optical block 51 and receiver controller; Spin photodetector 52, the receiving end 522 of spin photodetector 52 is integrated to the second end of light transmission device 70 through receiving optical block 51; The receiving flexible circuit board 53 is connected at its first end to the output end of the spin photodetector 52, and at its second end to the receiving controller.

[0045] In this embodiment, the optical receiver 50 includes a receiving optical block 51. To ensure reception accuracy, the receiving optical block 51 can be designed accordingly using the design of the transmitting optical block 61 described in the above embodiment. This ensures that the spin photodetector 52 accurately receives the optical signal, converts the optical signal into an electrical signal, connects the first end of the receiving flexible circuit board 53 to the output end of the spin photodetector 52, and connects the second end of the receiving flexible circuit board 53 to the receiving controller. The electrical signal is then processed to obtain optical communication data, thus completing the optical communication process. For example, if only data transmission is required, the spin photodetector 52 can be used solely for data storage. Further, refer to... Figure 5 , Figure 5 This is a schematic diagram of an optical communication system in the optical communication method of this application. In this case, the optical transmission device 70 connects the optical transmitter 60 and the optical receiver 50, thereby completing the optical communication between the optical transmitter 60 and the optical receiver 50. For example, the spin photodetector 52 and the optical transmitter 62 are directly designed on the corresponding optical blocks, and then connected to the controller through their respective circuit boards to realize the entire optical communication control process.

[0046] In one embodiment, the optical receiver 50 and the optical transmitter 60 can be located at the same end. In this case, since the optical receiver 50 uses a spin photodetector 52 to receive optical signals, the size of the spin photodetector 52 can be smaller than the size of the optical transmitter 62 in the optical transmitter 60. However, due to the inherent properties of the spin photodetector 52, this arrangement will not affect normal optical reception. Furthermore, when the optical receiver 50 and the optical transmitter 60 are located at the same end (used in scenarios where optical communication achieves communication isolation), a flexible circuit board can be used to implement electrical connections, thereby reducing the overall cost of optical communication and making the layout more flexible.
