Paper Abstract

We propose a new waveguide resonator device with a mirror cavity and a multimode interference (MMI) coupler. We present simulation results for the silicon wire MMI coupler with suppressed reflections and its use as a coupling element in the resonator cavity, built on the silicon-on-insulator waveguide platform. Tapering structures used in the reflection suppression were optimized, and the wavelength dependency of a conventional MMI was compared to that of the MMI with reflection suppression. Two-mirror MMI coupled resonator was studied using finite difference time domain simulation by both pulse and continuous wave excitation. The optimal resonator has a very small footprint of 3 μm × 29.7 μm, with a quality factor of 774.
