Paper Abstract

We propose a method of multiple grating formation in a photorefractive crystal by using a single diffractive mask. The diffractive mask is composed of several spatial frequency components so that the propagating optical wave produces three-dimensional interference patterns in the crystal. We note that it is a system of amplitude and phase gratings having various spatial frequency spectrum. The recorded pattern then can control the flow of another optical wave (signal wave) with different wavelength. This is an integrated version of the conventional hologram multiplexing technique in time domain. The recording and signal wavevectors are determined to satisfy the phase matching condition through the recorded pattern (i.e. Bragg grating). Because this recording method excludes complex time scheduling and mechanical movement of the conventional multiplexing, it provides stability and compactness in the recording procedure for mass production and can make optical devices possessing multiple Bragg gratings.
