ABSTRACT:
A cross point of an N.times.M optical switching network is defined by a pair of switches, a first of which couples optical information from a row waveguide to a bypass waveguide. The second switch couples the information from the bypass to a column waveguide. An optical eraser may be employed to absorb any information not switched. The eraser is positioned along the row waveguide downstream of the cross point. Each switch at a cross point as well as the eraser includes actuators which, in fiber optic embodiments, move the respective elements of the switch (or eraser) from positions at which only negligible coupling occurs to more closely spaced positions at which significant coupling occurs, upon command.
