An optical switching system employing switching modules. Each module comprises (a) a source channel, (b) a transmitting element, (c) a receiving element, and (d) a destination channel. The transmitting element directs the source channel signal to a destination channel. The transmitting element includes an initial beam deflector and a beam deflection amplifier. The receiving element includes a beam deflection compressor and a beam aligner. One embodiment of the initial deflector is a pair of focusing lenses, one of which is displaced by a piezoelectric actuator. When one lens is displaced a distance d, the output light beam has a deflection angle &agr;=(f1+f2)/f2. The beam deflection amplifier multiplies the small angle &agr; by a transfer function F to result in a beam with a deflection angle F&agr;. The receiving element is the transmitting element in reverse. The first system configuration connects a single channel to one of a number of channels. The second system configuration connects a group of M channels with another group of N channels. The third system configuration cross-connects N channels in an arbitrary manner.
