Volume Phase Transmission Gratings and Compact Configurations for Coarse Wavelength Division Multiplexing and Demultiplexing

Abstract

Volume phase transmission gratings, that have high and uniform diffraction efficiency regardless of polarization of the incident light over a broad wavelength range, have been designed and recorded. Such gratings were incorporated successfully into a novel compact configuration of a coarse wavelength division demultiplexer. Calculated and experimental results of such gratings, and a compact four-channel demultiplexer operating in the 1500 nm to 1600 nm range are presented.
