摘要

Abstract

Matrix computation

as a fundamental building block of information processing in science and technology

contributes most of the computational overheads in modern signal processing and artificial intelligence algorithms. Photonic accelerators are designed to accelerate specific categories of computing in the optical domain

especially matrix multiplication

to address the growing demand for computing resources and capacity. Photonic matrix multiplication has much potential to expand the domain of telecommunication

and artificial intelligence benefiting from its superior performance. Recent research in photonic matrix multiplication has flourished and may provide opportunities to develop applications that are unachievable at present by conventional electronic processors. In this review

we first introduce the methods of photonic matrix multiplication

mainly including the plane light conversion method

Mach–Zehnder interferometer method and wavelength division multiplexing method. We also summarize the developmental milestones of photonic matrix multiplication and the related applications. Then

we review their detailed advances in applications to optical signal processing and artificial neural networks in recent years. Finally

we comment on the challenges and perspectives of photonic matrix multiplication and photonic acceleration.
