Abstract
A space-division optical switching system comprising a multichannel acousto-optical deflector between a plurality of inlet fibers and a plurality of outlet fibers, together with both a plurality of inlet microlenses for collimating beams from the inlet fibers on the deflector and also, downstream from the deflector, a Fourier lens with the said deflector being located in the focal plane thereof, the system including a second multichannel acousto-optical deflector disposed downstream from said lens in the image focal plane thereof, together with a plurality of outlet microlenses serving to focus the beams from the second deflector on the outlet fibers.
