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 ...

Bragg Grating Cavity Design Using Bragg Gratings
International Journal For Multidisciplinary Research, 2023 The aim of the experiment is to design Bragg Grating Cavity design (to show Fabry Perot effects) for High Quality Factor. The basic Bragg Grating design used in this project consists of two identical Bragg Gratings and a cavity between the two Gratings. Bragg devices are first simulated using Transfer Matrix Model (TMM) on MATLAB.

Modified coupled-mode model for thermally chirped polymer Bragg gratings [PDF]
, 2010 A modified coupled-mode (CM) model is proposed for the optical behavior of thermally chirped Bragg gratings. The model accounts for the axial gradient in the modulation wavenumber, which has been ignored in the classical CM model. The model is used to
