Photonic Bragg gratings with cladding asymmetry for polarization independent and rotation filter

We present a single-etched polarization-independent Bragg filter using cladding asymmetry. An air cladding strongly couples TE and TM modes, rotating its polarization status and achieving polarization-insensitive Bragg reflection at the average of both Bragg wavelengths.
