Polarization independent Bragg gratings using tilted subwavelength grating waveguide Bragg gratings
Optics Express, 2023 We propose and experimentally demonstrate a polarization independent subwavelength grating (SWG) waveguide Bragg grating (WBG) by using an SWG waveguide with tilted segments. By optimizing the tilting angle and other geometry parameters, such as the width and the length of the loading segments used to create the BG, we can obtain a zero birefringence ...
