This paper discusses the architecture of an N X N optical spatial switch in which independent and arbitrary switching is realized using diffraction of light beams by a microhologram array (MA) programmed by two 1 X N acousto-optical elements. It is shown that a bacteriorhodopsin film can be used as a recording medium for MA. The throughput of each channel, being up to several Gbit/s the capacity of such a switch, can reach 104 X 104 channels, the time of an arbitrary switching being not more than 100 ms. Experimental results are given proving the possibility of implementing a switch having said characteristics.
