Description

Technical Field

[0001] The invention relates to the field of integrated circuits and optoelectronic chips, and in particular to a programmable optoelectronic integrated system development platform. Background Art

[0002] With the rapid development of information technology, optoelectronic integration technology, as an important foundation for future information processing and transmission, is becoming the focus of research in multiple fields. Traditional electronic integrated systems have reached their physical limits in terms of information processing speed and bandwidth capabilities, and photonic integration technology, by utilizing the high-speed transmission and broadband characteristics of photons, can significantly improve system performance while reducing power consumption. Therefore, photonic integration technology has broad application potential in high-speed communications, data centers, artificial intelligence processing, and precision sensing. However, the development of existing photonic integrated systems usually relies on a fixed hardware architecture, is bound to specific application scenarios, and lacks sufficient flexibility. At the same time, the development process is complex, involving collaborative design in multiple disciplines, and is difficult to meet rapid iteration and diversified needs.

[0003] At the same time, Moore's Law is coming to an end, and the evolution and iteration of traditional electronic chips are gradually slowing down. Photonic chips have become an important direction for the development of integrated circuit and semiconductor chip technology in the post-Moore era with their advantages in high bandwidth, low latency, low power consumption, and multi-functions. However, the industrial chain of photonic chips is far less mature than that of electronic chips, and the packaging and testing costs of chips are high. At the same time, due to the insufficient logical capabilities of optical domain processing, photonic chips must be integrated with electronic chips, adapter circuits, and software algorithms to form a complete system with certain functions. Therefore, the construction of optoelectronic integrated systems often involves a large number of optical and electrical domains, as well as complex system problems caused by large-scale interactions in the optoelectronic domains. It is difficult to trace the source, complex to debug, and extremely time-consuming and labor-intensive.

[0004] In order to solve these problems, a unified and programmable optoelectronic integrated system development platform is urgently needed to support users' flexible configuration of optical signal modulation, behavior control and signal detection, while providing convenient development interfaces and efficient central processing resources. Such a platform can not only significantly reduce the development threshold of optoelectronic integrated technology, but also adapt to the application requirements of different scenarios and promote the widespread popularization of photonic integrated technology.

[0005] In the prior art, the publication number CN118231393A discloses a 3D optoelectronic integrated system and its preparation method, including an electric chip and an optical chip; the optical chip includes a buried oxide layer, a top silicon layer, a cladding layer and an inverted cone coupler, the cladding layer is arranged on the upper surface of the buried oxide layer, the top silicon layer is arranged in the cladding layer and contacts the upper surface of the buried oxide layer; the optical chip is also provided with an oxide layer through hole that penetrates from the upper surface of the cladding layer to the lower surface of the buried oxide layer, and the upper and lower ends of the oxide layer through hole are respectively provided with a metal pad and a solder ball; an electrode is provided above the top silicon layer and near the surface of the cladding layer, the electrode is connected to the top silicon layer through a micro hole, and a metal pad and a solder ball are provided on the upper surface of the electrode; the electric chip is flipped on the optical chip, and the electric chip is interconnected with the optical chip through the solder ball. However, the preparation complexity of this scheme is high. In this scheme, the optical chip includes a variety of complex structures such as a buried oxide layer, a top silicon layer, a cladding layer, and an inverted cone coupler, and these structures need to be prepared by precise micro-nano processing technology. In particular, the design and processing of the inverted cone coupler requires high process precision, and the coupling efficiency is easily reduced due to processing errors. At the same time, it cannot be flexibly adjusted and has a strong reliance on fixed hardware architecture, which reduces the adaptability and development efficiency of the system.

DETAILED DESCRIPTION

[0017] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0019] See also Figure 1-Figure 3 , the present invention provides a technical solution: A programmable optoelectronic integrated system development platform, specifically comprising: An optical signal modulation module is electrically connected to the photonic integrated chip and is used to optically modulate system input data or signals and customize modulation properties in a programmable manner.

[0020] The hardware structure of the optical signal modulation module includes a voltage or current source with a certain driving capability and definable output characteristics (such as a digital-to-analog converter DAC), as well as a driven laser, a broadband light source, a modulator, or a combination of these components. The scalable hardware interface also allows further adaptation of other components or devices. The input data and signals to be processed are driven by a voltage or current source with a certain driving capability under the control of the CPU to realize signals with specific wavelength, intensity, amplitude, phase, frequency, polarization, mode and other optical characteristics. The modulation format, time slot, duty cycle, chirp, etc. can also be adjusted or controlled by the central processing unit (CPU).

[0021] The frequency of the light wave can be modulated by synthesizing multiple signals of different frequencies. For example, direct digital synthesis (DDS) technology is used to generate accurate frequency synthesis signals through a digital-to-analog converter (DAC), thereby achieving frequency modulation of the light source. DDS can generate very high-precision, low-noise frequency signals, which are suitable for high-precision modulation.

[0022] Optical signal modulation modules rely on high-precision and high-speed DACs (digital-to-analog converters) to convert digital signals into analog signals. In order to achieve more precise modulation, it is key to select a high-resolution (12-bit, 14-bit or higher) DAC. For example, AD9747 and MAX5862 are both typical high-precision, wide-bandwidth DACs suitable for high-speed signal modulation.

[0023] The modulator may be an electro-optic modulator, such as a LiNbO3 electro-optic modulator, which is a key component for achieving high-precision phase, frequency, and amplitude modulation. They are usually made of materials such as lithium niobate (LiNbO3) or potassium niobate (KTP), and can adjust the propagation characteristics of optical signals, such as the phase and intensity of light, through an electric field. Electro-optic modulators have a high modulation bandwidth and can meet the requirements of applications such as high-speed optical communications and quantum communications.

[0024] Polarization can be controlled by a polarization controller. In some applications, the polarization state of light has an important impact on signal transmission. For example, the use of a liquid crystal optical modulator (LCOM) can achieve precise polarization control of optical signals, so that optical signals are transmitted in a specific polarization state, improving system performance.

[0025] An optical behavior control module is electrically connected to the photonic integrated chip, and is used to configure the optical response behavior of the system, control the optical transmission behavior of the photonic integrated chip, and support customization of configuration properties in a programmable manner.

[0026] The typical hardware structure of the optical behavior control module includes a multi-channel programmable power supply, which can directly control the phase shifter, adjustable attenuator and other unit devices on the photonic integrated chip, or a combination of these units, to achieve programming of properties such as waveguide phase shift, link gain or loss, and spatial refractive index distribution, thereby controlling the on-chip optical transmission behavior of the photonic integrated chip.

[0027] The phase shifter is used to change the phase of the optical signal in the waveguide, thereby realizing interference, path selection, wavelength control and other functions. By changing the phase, the propagation behavior of the optical signal can be controlled. The specific control principle is as follows: For the thermo-optic phase shifter, the thermo-optic phase shifter sets a heater electrode near the waveguide and uses the thermo-optic effect (the refractive index of the material changes with temperature) to change the refractive index of the waveguide material. The programmable power supply provides precise current or voltage to the heater to control its heat generation, thereby adjusting the refractive index change in the waveguide, and finally realizing the phase control of the optical signal; For electro-optic phase shifters, the electro-optic effect is used to adjust the refractive index of the waveguide material. A programmable power supply applies a specific voltage to the electrode to generate an electric field and induce a change in the refractive index, thereby changing the phase of the optical signal in the waveguide.

[0028] The adjustable attenuator is used to precisely control the intensity of the optical signal and realize dynamic adjustment of the link gain or loss. For example, the optical signal intensity can be balanced by adjusting the attenuation to optimize the system performance. Based on the liquid crystal adjustable attenuator, the electro-optical properties of the liquid crystal are used to change the refractive index of the liquid crystal layer through an external electric field, thereby introducing controllable light attenuation. The programmable power supply generates a dynamic voltage to control the orientation angle of the liquid crystal, thereby adjusting the intensity of the optical signal; The adjustable attenuator based on the thermo-optical effect sets a thermal control area near the waveguide, changes the absorption characteristics of the waveguide or generates diffraction loss by heating, and then adjusts the intensity of the optical signal. The programmable power supply provides precise current or voltage to the thermal control electrode to control the attenuation by adjusting the heat. The adjustable attenuator based on micromechanical devices uses MEMS (micro-electromechanical system) technology to change the coupling efficiency of the optical signal through the micromechanical structure, thereby achieving attenuation control. A programmable power supply applies voltage or current to the MEMS actuator to control the movement of the mechanical structure and achieve light attenuation adjustment.

[0029] Among them, the phase shift of the optical signal in the waveguide determines the interference effect and the optical behavior of the waveguide network (such as path selection, phase difference control, etc.). More complex optical functions can be achieved by precisely adjusting the waveguide phase shift. The waveguide phase shift is mainly achieved by adjusting the refractive index of the waveguide material or the length of the light propagation path. Waveguide phase shift control based on the electro-optical effect: voltage is applied to the electrodes near the waveguide through a programmable power supply to generate a local electric field to change the refractive index of the waveguide, thereby achieving optical phase shift.

[0030] For link gain and loss, the programmable power supply provides precise current to the amplifier to control its gain and achieve power boost of the optical signal; the programmable power supply controls the working state of the attenuator to adjust the loss of the optical signal.

[0031] An optical signal detection module is electrically connected to the photonic integrated chip, and is used to detect the modulated optical signal generated by the photonic integrated chip, and convert the detected optical signal into an electrical signal, and supports the customization of detection properties in a programmable manner.

[0032] The hardware components of the optical signal detection module include a light detector, an optical power meter, or a combination of these components. The expandable hardware interface also allows for further adaptation of other components or devices. These components or devices convert optical signals into electrical signals, which are quantized into digital electrical signals by the analog-to-digital converter ADC and further processed or analyzed by the CPU. The programmable properties of the detection module include but are not limited to gain, receiving intensity range, trigger mode, integration time, number of sampling points, etc.

[0033] Among them, the photodetector is the core component of the detection module, which is used to convert the optical signal (optical power) into an electrical signal. Common types of photodetectors include: PIN photodiode: suitable for medium and low speed applications, linear response, low noise; avalanche photodiode (APD): through the built-in gain mechanism, suitable for low optical power and high sensitivity detection; photomultiplier tube (PMT): suitable for high gain detection under extremely low optical power, but the cost is relatively high.

[0034] An optical power meter is used to accurately measure the average power of an optical signal. It is usually composed of a photodetector and a signal processing circuit. It calculates the optical power per unit time by integrating the current output of the optical signal.

[0035] The expandable hardware interface allows other components or devices (such as spectrometers, wavelength meters, external detectors) to be connected to the module to adapt to more functional requirements, such as current amplifiers for amplifying very weak light detection signals; local sampling devices for high-speed data acquisition or special signal processing.

[0036] As for programmable properties and implementation methods, the programmable properties of the optical signal detection module make it highly flexible and meet the needs of different application scenarios. The following lists each programmable property and its specific implementation method: Gain refers to the degree of signal amplification and is used to adjust the output voltage or current amplitude of the detector to adapt to different optical power levels. The amplifier at the back end of the detector (such as a transimpedance amplifier or a voltage amplifier) ​​provides gain adjustment capability. The programmable power supply or digital control circuit adjusts the gain ratio of the amplifier. The user configures the gain parameters through the software interface, and the central processor adjusts the hardware gain level through the control signal.

[0037] The receiving intensity range determines the dynamic range of optical power that the module can detect. For optical signals of different intensities, different transimpedance amplifier parameters are used to adapt to the wide dynamic range.

[0038] The trigger mode determines when the detection module starts data acquisition or processing. The user defines the trigger conditions through the interface, such as timing trigger, external input trigger or intensity trigger.

[0039] The integration time determines the length of time the detector samples and accumulates the signal, affecting the signal-to-noise ratio and power measurement accuracy. The CPU accumulates sampling points within a preset time through a timing mechanism to achieve an adjustable integration time.

[0040] The number of sampling points refers to the number of points captured by the ADC during signal processing, which affects the resolution and calculation accuracy of waveform reconstruction. The user sets the number of sampling points through the interface, and the driver controls the sampling parameters of the ADC.

[0041] The central processing unit is electrically connected to the optical signal modulation module, the optical behavior control module and the optical signal detection module, and is used to control and schedule various functional modules in the system and provide computing resources for data and signal analysis and processing.

[0042] Among them, the central processor coordinates the collaborative work of each module through the interface electrically connected to each module (modulation module, control module, detection module), and the management module workflow includes: generating and distributing control signals to ensure that each module operates according to the specified time sequence and operation mode, and realizing logical control between modules, such as transmitting the modulated output of the optical signal to the optical behavior control module for processing; Task scheduling methods include: dynamically allocating computing resources and control signals to modules, adjusting priorities according to system requirements, and ensuring the synchronization of module operations through time synchronization mechanisms (such as clock-based trigger signals) to avoid data competition or signal delays.

[0043] The central processing unit has powerful computing power and is used to process the digital data of optical signals. The optical signal modulation data processing includes: analyzing the input signal (such as data encoding, waveform generation) and generating modulation parameters, supporting real-time calculation of multiple modulation formats (such as amplitude modulation, phase modulation, polarization modulation, etc.).

[0044] The processing of optical signal detection data includes: analyzing the digital data from the detection module, such as calculating the optical power, signal waveform characteristics, and noise level; performing signal processing tasks such as filtering, denoising, power integration, and spectrum analysis.

[0045] The analysis of optical transmission behavior includes: analyzing the feedback data of the optical behavior control module, such as phase shift, gain and loss changes; adjusting the control parameters based on the analysis results to achieve closed-loop control.

[0046] The central processor and its interaction with various components of the programmable optoelectronic integrated system platform are implemented in hardware through a commercial embedded system or a combination of several commercial embedded systems; The CPU and the above-mentioned optical signal modulation module, optical signal detection module and optical behavior control module can be integrated into a programmable optoelectronic integrated system development platform through commercial embedded system hardware, field programmable logic gate array (FPGA) and its peripheral board-level circuits, or application-specific integrated circuits (ASIC) or system-on-chip (SOC), or their appropriate combination.

[0047] By making different programming definitions for the optical signal modulation module, the optical signal detection module, and the optical behavior control module, combined with the control scheduling of the central processor and the processing and analysis of the input and output data, the programmable optoelectronic integrated system development platform can be reconstructed into an optoelectronic system with various functions for different series of application scenarios. Systems with different functions and corresponding programs can be further combined to realize more complex integrated systems for a variety of application scenarios, such as optical transmission, optical interconnection, optical computing, optical switches, optical phased arrays, optical gyroscopes, etc.

[0048] In certain application scenarios, the optoelectronic integrated system only needs to use some but not all of the hardware functional modules, and the corresponding system development method may only need to use some but not all of the steps included. The execution order of the steps is not fixed, but adjustment is allowed.

[0049] Therefore, this programmable optoelectronic integrated system development platform has a high degree of versatility and can be flexibly applied to a variety of different work scenarios. This platform can support the decoupling of hardware system construction and software programming development, effectively reducing the difficulty of implementing optoelectronic integrated systems, avoiding unnecessary customized development in a large number of optoelectronic system applications, and improving the reusability of hardware solutions. Furthermore, the system development platform and development method also support scalable hardware and software interfaces, the software interface supports the design and development tools of photonic and electronic integrated chips, and the hardware interface provides expansion of more different types of optical signal modulation modules, optical signal detection modules and optical behavior control modules, or other related equipment. These excellent features enable the rapid deployment and rapid iteration of new photonic chip technology solutions.

[0050] The attribute configuration and operation processing are integrated and unified in a high-level programming language development environment to construct different optoelectronic system functions, wherein the high-level programming languages ​​include C, C++, VB, JAVA and Python.

[0051] The system development platform integrates attribute configuration and operation processing into a unified programming development environment, and is used to build various optoelectronic system functions based on high-level programming languages ​​without directly using hardware description languages ​​such as VHDL, thus achieving the decoupling of hardware system construction and software programming development.

[0052] The programmable optoelectronic integrated system development platform has scalable software and hardware interfaces. The software interface supports design and development tools for photonic and electronic integrated chips, and the hardware interface provides expansion of different types of optical signal modulation modules, optical signal detection modules, and optical behavior manipulation modules.

[0053] The development method of the programmable optoelectronic integrated system development platform is implemented using high-level language programming, specifically including: The CPU reads system platform configuration information from the program file, the platform configuration information including CPU information, optical signal modulation module, optical signal detection module and optical behavior control module information; The CPU executes the code in the program file to set the functional properties of the optical signal modulation module, the optical signal detection module and the optical behavior control module; Execute program code to read or generate system input data from files; The program code is executed to optically modulate the input data through the optical signal modulation module, and the generated modulated signal is passed through a link or system with certain optical transmission characteristics controlled by the optical behavior control module to generate an optical output, which is captured by the optical signal detection module and converted into an electrical signal by the optical signal detection module; The program code is executed to process the electrical signal converted and output by the optical signal detection module. The processed data is continuously used as input; the program code is continuously executed in sequence, or in a loop, or in a jump, to perform signal modulation, transmission and detection, as well as signal analysis and processing, until the entire program is completed, the optoelectronic system executes the function defined by the program code, and the output data (if any) is transferred or forwarded to the output device.
