Paper Abstract

A polarization-independent racetrack type micro-ring resonator formed by silicon-on-insulator slot waveguides with a phase compensation section included was investigated and proposed. By tuning the ratio of lengths of the slot waveguide and the channel waveguide the cumulative phase difference between quasi-TE and quasi-TM modes can be well eliminated which allows for a polarization independent operation over a wide spectral range. The finesses are 226 and 225 for the quasi-TE and quasi-TM modes respectively, with a free spectral range of 9 nm achieved as well as a compact device size of 30 μm, while delivering a good polarization-independent performance with the resonance mode mismatch less than 0.5 nm.
