dc.description.abstract | A photonic Bragg grating is a fundamental building block that reflects the direction of wave propagation through spa-tial phase modulation and can be implemented using sidewall corrugation. However, due to the asymmetric aspect ratio of a waveguide cross section, typical Bragg gratings exhibit a strong polarization sensitivity. Here, we show that pho-tonic Bragg gratings with cladding asymmetry can enable polarization-independent notch filters by rotating input polarizations. Such Bragg gratings strongly couple trans-verse electric (TE) and transverse magnetic (TM) modes propagating in opposite directions, filtering the input sig-nal and reflecting the rotated mode. We analyzed this polarization-rotating Bragg grating using the coupled-mode theory and experimentally demonstrated it on a silicon -on-insulator platform. Our device concept is simple to implement and compatible with other platforms, readily available as polarization transparent Bragg components.(c) 2023 Optica Publishing Group | - |
