Design of polarization-insensitive ring resonators in silicon-on-insulator using MMI couplers and cladding stress engineering
Abstract
A novel silicon-on-insulator (SOI) ring resonator design is described that uses a 2 × 2 multimode interference coupler to achieve polarization-independent coupling, and cladding stress induced birefringence control to eliminate the difference in round-trip phase accumulation between the transverse-electric and transverse-magnetic polarized modes. The design parameters are determined for polarization-independent SOI ring resonators with couplers …
