Abstract

The invention discloses an optical vector-matrix multiplier based on a single-waveguide coupling micro-ring resonant cavity, which comprises a substrate, a buried layer and a top layer, wherein the buried layer is manufactured on the substrate; the top layer is manufactured on the buried layer; a comb structure is etched on the top layer; the comb structure comprises a back part and a tooth part; tunable micro-ring resonant cavities are etched in the side direction of the tooth part; each tooth of the tooth part is coupled with the plurality of adjacent tunable micro-ring resonant cavities to form a cascaded multi-wavelength modulator; an input end of an optical signal is formed in the centre of the back part of the comb structure; and an output end of the optical signal is formed at the tail part of the tooth part of the comb structure.

Description

technical field [0001] The invention relates to the technical field of optical information processing, in particular to an optical vector-matrix multiplier. Background technique [0002] Optical vector-matrix multiplier is a widely used optical system in the field of optical signal processing. The earliest optical vector-matrix multiplier model was proposed by J.W.Goodman of Stanford University in the United States, and it is usually called "Stanford vector-matrix multiplier". The optical vector-matrix multiplier mainly includes three parts, namely a light source array, a matrix mask and a detector array. Firstly, using a row of light-emitting diodes as the input vector, arrange the light path between the light-emitting diode array and the matrix mask so that each light-emitting diode only illuminates one column of the matrix mask, and then arrange such light path behind the matrix mask so that the light from the matrix mask The light from each row of the mask is focused o...
