A scheme is presented for an optical spatial switch in which independent and arbitrary switching is realized using diffraction of light beams by a programmable microhologram array (MA). It is shown that a bacteriorhodopsin film can be used as a recording medium for an MA. If the throughput of each channel is up to several Gbit/s, the capacity of such a switch can reach 104 x 104 channels, with the time of an arbitrary switching not more than 100 ms. The experimental results given prove the possibility of implementing a switch having these characteristics
