Abstract
A technique to record local non-volatile photorefractive holograms is developed by using the spatially selective UV sensitization in a photochromic Fe:Mn:LiNbO3 crystal. Correspondingly, the integrated modules of WDM Multiplexer/Demultiplexer, Add/Drop, Crossbar, and Cross-Connect are designed, and the proof-of-principle experiments are given.
