Abstract

The invention discloses an optical circuit, an optical signal processing method, an optical signal processing device, optical signal processing equipment and a readable storage medium. The optical circuit is characterized in that one optical output end of a first MZI is connected with one optical input end of a third MZI; one optical output end of the second MZI is connected with the other optical input end of the third MZI; two optical input ends of the first MZI and two optical input ends of the second MZI are respectively connected with optical signals corresponding to a 2*2 convolution sequence to be multiplied; the first MZI, the second MZI and the third MZI respectively carry out phase shift on input optical signals of the first MZI, the second MZI and the third MZI so as to realize convolution calculation; and one optical output end of the third MZI outputs a light signal carrying a convolution result. According to the optical circuit, the number of MZIs is smaller, and a structure is simpler; compared with 2*2 convolution operation achieved in a Gridnet mode, half of time loss and equipment loss can be saved, a convolution calculation speed can be increased, and the structure of an optical device can be simplified.

Description

technical field [0001] The present application relates to the field of computer application technology, in particular to an optical circuit, an optical signal processing method, device and readable storage medium. Background technique [0002] In recent years, people's demand for optical computing technology has increased rapidly. Optical computing can be divided into analog optical computing and digital optical computing. One of the most typical examples of analog light calculations is Fourier operations, which require the use of Fourier transform-related calculations, such as convolution calculations, in areas such as image processing. Using a traditional computer to calculate the Fourier transform is very computationally intensive, and the process of light passing through the lens itself is a Fourier transform process, which takes almost no time at all. Digital optical computing uses the combination of light and optical devices to form classic logic gates, constructs a ...
