Paper Abstract

An optical crossbar switch is proposed which uses a semiconductor-addressed, deformable-mirror spatial light modulator to direct gigabit per second optical transmissions to several receivers. The switch performance is described in terms of mirror element size, deflection range and number of modulator elements, as well as emitter, detector and lens dimensions. These parameters are incorporated in a link energy budget and also provide estimates of system dimensions. Maximum-sized 128 to 1000 channel crossbars appear feasible based on the performance of various lightwave components.
