Abstract
Volume holograms stored in a photorefractive crystal have been used as routing templates for an optical communication switch. These holograms are recorded and read out by using coded object beams. A spatial light modulator is used to modulate the object beam with different addresses, such that the coded signal is routed from an input channel to a desired output channel. In this paper the maximum number of channels that can be addressed and hence the maximum number of equal-diffraction-efficiency holograms that can be stored in the photorefractive crystal for a given bit error rate are presented.
