title: Unidirectional star coupler for single-fiber distribution systems.
abstract: The design and construction of a unidirectional star coupler for single-fiber distribution systems are described. A rectangular mixing section is required to obtain uniform output distribution. Four-port stars have been constructed with losses only (1/2) to 1 dB greater than packing fraction. For any given input, outputs are uniform to within about +/-1 dB.
