Advances in Waveguide Bragg Grating Structures, Platforms, and Applications: An Up-to-Date Appraisal
A Bragg grating (BG) is a one-dimensional optical device that may reflect a specific wavelength of light while transmitting all others. It is created by the periodic fluctuation of the refractive index in the waveguide (WG). The reflectivity of a BG is specified by the index modulation profile. A Br...
