A novel architecture for a reconfigurable optical routing switch using photorefractive crystals with nondestructive readout is presented. This design reduces the order of complexity from n2 to n for a general two-wavelength n × n holographic interconnection network. The packing capacity of the network is discussed and is calculated to be of the order of 1000 × 1000 for an ideal volume holographic recording material. In practice, we show that the actual value is constrained by the number of gratings that can be multiplexed in a single photorefractive crystal. A 2 × 3 switch is demonstrated by using a Bi12GeO20 crystal with 514-nm writing beams and 633-nm signal (readout) beams.
