There is a recent trend to reduce waveguide based silicon photonic devices to the sub-micron regime for increased chip density and better cost efficiency. However, designing polarization independent (PI) ring resonator using submicron waveguide is a challenge as it exhibits strong polarization dependency. We demonstrate theoretically the feasibility of realizing both single-mode (SM) and PI operation in ring resonator based on sub-micron silicon-on-insulator (SOI) rib waveguides. A resonance spectra misalignment that represents only 11% of the full-width half-maximum (FWHM) linewidth of 1.64nm is achieved, with a free spectra range of 13nm.
