Abstract: A photonic integrated circuit (“PIC”) bandpass filter with polarization diversity can comprise a polarization management stage operable to receive a polarization diverse light input and to output an intermediate beam having a uniform polarization, and a filter stage operable to receive the intermediate beam from the polarization management stage, to filter the intermediate beam, and to output a filter output beam. Energy from both an in-plane polarization and an out-of-plane polarization of the polarization diverse light input can thereby be transferred to the filter stage.
