ABSTRACT:
An optical cross-connect switch is disclosed which includes a plurality of optical input fibers, a plurality of optical output fibers and a plurality of the (1×N)-switches ganged together. Each of the switches includes a state selector, a lens for collimating light from a single one of the optical input fibers, a plurality of output coupling lenses, each of which corresponds to one of the optical output fibers, and a beam shaper for focusing light from the state selector onto a selected one of the coupling lenses for further focusing of the light onto the corresponding optical output fiber. Alternatively, the optical cross-connect switch can be a single an (L×K)-switch which includes a plurality of state selectors and a plurality of lenses for collimating light from the plurality of optical input fibers.
