CHANNEL-DROPPING FILTER HAVING TWO RESONATORS FOR COUPLING THE TWO POLARISATION COMPONANTS

摘要

A polarization diversity scheme for managing the polarization dependence of a microring resonator which employs two resonators serially arranged and constructed to separately filter transverse electric (TE) and transverse magnetic (TM) polarization components of a predetermined wavelength in a randomly polarized DWDM optical signal, and to recombine the separately filtered components prior to output from an optical component employing the inventive polarization diversity scheme.
