Directly UV-written planar channel waveguides containing simultaneously defined Bragg gratings

Directly UV-written planar channel waveguides containing simultaneously defined Bragg gratings

A new technique for the simultaneous writing of channels and Bragg gratings uses interfering focused UV beams in a photosensitive silica layer and is able to fabricate near-ideal Bragg gratings, with 60% reflectivity.
