Optical TDM switch architectures with distributed control

We propose an optical TDM switch architecture using O(log/sup 2/ N) 2/spl times/2 single-bit controlled optical switching elements for interchanging time slots in a 1/spl times/ N TDM frame. The distributed single-bit control is obtained on the fly at each switching element. The switch also improves on traditional TDM cross-connect systems by allowing the simultaneous delivery of multiple time slotted packets to a single destination.
