By using volume holography characteristics, optical devices having demultiplexer and/or dispersion compensator capabilities are proposed which can control multiple channel wavelengths in the wavelength division multiplexed (WDM) system. Through a specially designed mask system, multiple volume gratings corresponding to the multi-channel components are recorded in a photorefractive crystal. This mask recording scheme simplifies the conventional sequential multiplexing procedure which requires complex mechanical or laser source system. Recording schemes and device characteristics of the above devices are presented in relation with volume diffraction principle and photorefractive crystal properties.
