We present a novel design for a reconfigurable silicon microring resonator filter exploiting non-integer Vernier ratio to achieve FSR-free spectral response. Hitless tunability across the extended C+L band (1520 nm-1620 nm) is achieved by introducing controllable loss in the MRRs of the filter.

Abstract

We present a novel design for a reconfigurable silicon microring resonator filter exploiting non-integer Vernier ratio to achieve FSR-free spectral response. Hitless tunability across the extended C+L band (1520 nm-1620 nm) is achieved by introducing controllable loss in the MRRs of the filter.
