Abstract

The invention provides an optical switching device, including a substrate (10) having at least one polarization-selective multiplexing grating (H3) at least one polarization-selective demultiplexing grating (H4) and a polarization rotation element (6) acting as dynamic 1/2 lambda plate, optically interposed in the optical path between said multiplexing grating and said demultiplexing grating. The invention also provides a method for producing an holographic plate having a plurality of holographic elements. <IMAGE>
