A Novel Structure of passive ring waveguide resonator on silicon substrate

摘要

A novel optical waveguide rectangular ring resonator is designed and fabricated in silicon-on-insulator (SOI). The resonator is composed of four straight waveguides connected by four 90°directional change-turning mirrors. This merged structure allows compact size and low loss. The input and output waveguides to couple energy into and out from the resonator are also designed and optimized in this work.
