Abstract
Traditional spatial holographic devices are based on modification of the absorptive or dispersive properties of recording materials with dimensionality of one (gratings), two (holographic plates), or three (volume holograms). In this paper, the interest is in materials that, in addition to possessing the familiar spatial selectivity, respond selectively to various spectral components of the incident light. Spatial-Spectral Holographic (SSH) materials can implement all the processes associated with traditional spatial holography while simultaneously recording and processing the spectral/temporal characteristics of optical fields. Several memory, processing, routing, and communication devices have been proposed and demonstrated based on SSH.[1-15]
