Abstract

Based on the diffraction neural network, a small-volume diffractive optical element for optical logic calculation in the terahertz band is designed. The optical logic calculation ability and calculation accuracy of the diffraction neural network are calculated. The results show that after training, the diffraction neural network can accurately calculate eight kinds of optical logic and has 100% recognition accuracy when the number of network layers is greater than 5. This article mainly introduces the design principle and calculation process of the diffraction neural network, and compares the recognition accuracy of different network layers.
