OPTIMIZED DESIGN OF MMI COUPLERS BASED MICRORESONATORS

Abstract

This paper presents an optimized design for racetrack resonators based on Multimode Interference (MMI) couplers on the silicon on insulator (SOI) platform. The design approach takes into account the effects of bend and transition losses within the racetrack waveguide. For the first time, new positions and geometries of access waveguides are suggested and optimized to improve device performance.
