ABSTRACT:
An M.times.O multiplex/demultiplex device is disclosed. An M.times.N coupler is connected to an N.times.O coupler by phase shifting means. The phase shifting means provide N paths between the couplers, each path having an optical path length different from every other optical path length. The coupling region of the M.times.N coupler must provide for substantially uniform division of light power among the coupler branches when M are the launch ports. Similarly, the coupling region of the N.times.O coupler must provide for substantially uniform division of light power among the coupler branches when O are the launch ports. A preferred embodiment includes two fused waveguide fiber couplers with dissimilar waveguide fibers used as the phase shifting means.
