Recording of the Multiplexed Bragg Diffraction Gratings for Waveguides Using Phase Mask
The paper describes a stable method for multiplexed recording of the Bragg diffraction gratings for waveguides using a phase mask. Diffraction waveguides in this experiment were made of photo-thermo-refractive glass. Two types of the phase mask are considered: surface and volume. Their comparison is...
