Your grating has a surface that is textured with small grooves that change the thickness ever so slightly. The image at the left is the surface of one of our gratings under 80x magnification, taken by ...

Fiber Bragg gratings are used to turn an optical fiber into a sensing element by reflecting a specific wavelength back in the direction from which it came. New dissolvable fiber Bragg gratings can ...
