Producing bragg gratings in optical waveguides

We describe methods of producing gratings such as Bragg gratings with optical waveguides. Described are the writing and erasing of gratings within SiON waveguides by forming standing waves. Methods, systems, instruments, and devices are described that provide improved transmission of light through s...
