High-Performance Optical Convolutional Neural Network Accelerator with High-Speed Optical Modulator and Carrier-Injection-Type Attenuator

Optical convolutional neural networks have attracted attention because of their parallel processing capability. We demonstrated image restoration with sufficiently small MSE value using high-speed optical transmission system with a high-speed optical modulator and carrier-injection-type attenuators. 0.72 TOPS of multiple-accumulate operations were demonstrated both in simulation and experiment.
