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 Pet Supplements is specified by the index modulation profile.A Bragg grating is a flexible optical fil
