Problems solved by technology

The 2×4 optical switches that have been demonstrated so far are almost all combining two 1×2 optical switches, or using the principle of multi-mode interference to construct 2×4 optical switches, but these solutions will double the size of the device, or require more Long device length (more than 100 microns), not suitable for optical switch arrays and networks

Abstract

The invention discloses a track type micro-ring 2*4 thermo-optic switch prepared based on SOI material. The switch comprises a straight waveguide, a track type micro-ring waveguide prepared based on SOI material, and a thermal electrode arranged at the top layer. For the track type micro-ring waveguide, a bending waveguide and a short straight waveguide forms a closed track; coupling zones are formed between the track type micro-ring waveguide and direct waveguides; and the intersection parts of the direct waveguides employ multimode waveguide intersected structures. A digital electrical signal loaded by the thermal electrode arranged at the top layer is applied to realize rapid switching of optical channels. Therefore, simultaneous switching of the multi-input and multi-output optical signals can be realized; and the track type micro-ring 2*4 thermo-optic switch can be applied to working state detection of unit devices in the optical switch array, the optical routing, the optical logic gate design, and the integrated optical path.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a racetrack microring 2×4 thermo-optic switch prepared based on SOI material. Background technique [0002] With the rapid development of optical communication technology, the requirements for information transmission and processing are getting higher and higher. Integration, low loss, diversified functions, and strong anti-interference ability have become the goals pursued by developers of optical waveguide devices. What kind of material to choose to design waveguide devices is not only related to the performance parameters of the device, but also related to production costs, processing feasibility, and compatibility with existing systems. [0003] SOI (Silicon on Insulator, silicon on insulator) benefits from the large refractive index difference between silicon and silicon dioxide, so that optical signals can be well confined in silicon, and silicon ...
