Mass data processing technology is demanded in many fields related to national security, national economy and people's livelihood. Limited by electronic bottleneck, electrical processing technology starts to face the difficulty of meeting the requirements of high-speed and real-time processing of exponentially growing data. It is urgent to develop new potential mass data processing technology. Vector-matrix multiplication is an extremely important basic operation in many modern disciplines. Due to the intrinsic inherent parallelism and high-speed modulation of optics, adding an optical processing core to electrical processor is an efficient way to realizing high-performance computing system..This proposal intends to study the silicon-based integrated optical digital signal processor. We will focus on the study of the system design methodology of silicon-based integrated optical digital signal processor, structual design of silicon-based integrated optical digital signal processor (including high-speed, high-optical-bandwidth modulator array, fan-out and fan-in of optical vector, Wavelength addressable high-speed modulator matrix, the functional integration of optical digital signal processor), the manufacturing processs and characterization of silicon-based integrated optical digital signal processor. We plan to develop the silicon-based integrated optical digital signal processor with a computing speed of ten billion multiplication and accumulation per second at the termination of this proposal.
