Optoelectronic Multiplication Emulator Based on FPGA

Multiplication is a fundamental operation in artificial neural networks. We developed an optoelectronic multiplication emulator system, incorporating discrete optical components with an FPGA hardware. The system achieves high-speed, precise optical multiplications, validated by image convolution tests showing a mean error of 0.025. This emulator shows great potential for photonic neural network applications and establishes a strong foundation for advancing high-performance integrated photonic chips and optoelectronic computing systems.
