Abstract

Abstract An optical processor includes a non-linear ring resonator with lasers and two waveguides with electrodes positioned above them. This optical processor extends its functional range, i.e. providing multi-level processing of optical signals, an increase of power responsivity of input signals, increasing the number of optical contacts. In this optical processor, semiconductor lasers have been provided on the coupling waveguides. Optical mode mixers in coupling regions have been generated by connecting the waveguides and the ring resonator in coupling regions so that the following relationship is observed: an one-mode waveguide and a ring resonator make up a two-mode mixer, and electrodes are applied above the coupling regions.
