The OPTICAL ROUTER UTILIZING WAVEGUIDES COMBINED WITH BRAGG GRATINGS ON SILICON PHOTONIC

Abstract

— This paper presents the operating principle of a 1×2 optical router and the numerical simulation design of its constituent components. The optical router comprises arrayed waveguide grating (AWG) structures, waveguide Bragg gratings (WGBG), a 1×2 optical switch utilizing 2×2 multimode interference (MMI) couplers, and wavelength-selective routing based on microring resonators for six high-density wavelength channels in dense wavelength-division multiplexing (DWDM) applications. Computational results from localized simulations for each component demonstrate excellent optical performance, validating the adherence to the design principles. These favorable outcomes indicate significant potential for the proposed structure in high-density wavelength-selective routing devices for DWDM optical communication systems and high-speed optical interconnects.
