Abstract

A new method of switching high-bandwidth channels using directable optical beams has been developed.¹ The principal attributes of this method are capability of switching a large number of optical channels within a switching matrix, fast and accurate switching under computer control, and very low cross talk. To demonstrate the feasibility of the concept and to measure operational parameters, a 16-channel optical switcher was constructed. Figure 1 is a diagram of the 16-channel switcher. Any one of the 16 modulated transmitter beams may be directed to any one of the 16 detector elements, and all channels may be active simultaneously.
