High-speed optical switching integrated chip based on on-chip optical delay line

Abstract

The invention discloses a high-speed optical switching integrated chip based on an on-chip optical delay line, which comprises a chip substrate, an optical delay line and an optical switch array, the optical delay line is arranged on the chip substrate, the optical switch array is arranged on the chip substrate, and the on-chip optical delay line is arranged on the chip substrate. The input end of the optical switch array is connected with the output end of the optical delay line. The optical switch array comprises: N input ports; the plurality of optical switch units are connected with the N input ports; the M output ports are connected with the output ends of the optical switch units; the plurality of optical switch units are arranged according to a topological structure; the number of the optical delay lines is N, and the N optical delay lines are connected with the N input ports of the optical switch array in a one-to-one correspondence mode. The optical switching integrated chip is composed of N on-chip optical delay lines and an N * M optical switch array. Data are firstly input into the on-chip optical delay line to play a role in optical caching.
