title: Optical-fiber systems with nonreciprocal couplers.
abstract: The effectively nonreciprocal behavior of a single-mode to multimode optical-fiber coupler is discussed and results from polished couplers given. Two different applications in local-area networks and recirculating rings are investigated and the results presented.
