4*4 non-blocking optical router based on active micro-ring resonator

Abstract

The invention discloses a 4*4 non-blocking optical router based on an active micro-ring resonator. The optical router comprises four parallel waveguide micro-ring resonator 1*2 optical switches and four crossed waveguide micro-ring resonator 1*2 optical switches, wherein the four parallel waveguide micro-ring resonator 1*2 optical switches are connected to the four crossed waveguide micro-ring resonator 1*2 optical switches, so that the optical router comprises only four input terminals and four output terminals, and each waveguide corresponding to the component is sequentially coupled with four micro-ring resonators from the input terminals to the output terminals, wherein two micro-ring resonators are used for downloading the optical signals at the input terminals of the waveguides to the output terminals of the other two waveguides; and the other two micro-ring resonators are used for uploading the optical signals at the input terminals of the two waveguides to the output terminals corresponding to the waveguides, thus achieving the non-blocking router switch among four two-way communication ports.

Description

technical field [0001] The invention relates to the technical field of a switch for realizing routing switching among multiple ports in an on-chip optical network system, in particular to a 4×4 non-blocking optical router based on an active microring resonator. Background technique [0002] In the 1980s, R.A. Soref and others opened up a new field of silicon-based photonics. Because the large refractive index difference of the silicon waveguide makes it have a higher limitation on light transmission, not only the cross-sectional size of the waveguide can be reduced to the sub-wavelength level, but also the waveguide with a small curvature is allowed to bend. In terms of device integration, silicon-based photonic devices undoubtedly have great advantages. Secondly, the process of making silicon-based waveguide devices is compatible with the traditional CMOS process, so that mature processing technology can be used, and the hybrid integration of waveguide devices and microele...
