Abstract
An arrangement for optical multiplexing and demultiplexing. The multiplexer comprises an optical output waveguide and a plurality of optical input waveguides coupled to the output waveguide by nonblocking optical switches. An electrical activation signal at a switch causes light entering the switch through the associated input waveguide to appear on the output waveguide. The activation signals are provided by a pulse traveling down an electrode past the optical switches, such that parallel input signals on the input waveguides are time multiplexed onto the output waveguide to produce a serial output signal. A similar arrangement is provided for a demultiplexer comprising one input waveguide and a plurality of output waveguides.
