Abstract: PROBLEM TO BE SOLVED: To obtain an optical router which is easily producible from a not costly optical fiber element and does not require an optical device or integrated optical element of a bulk type by constituting the optical router of an electronic element (phase controller), a directional coupler made of a fiber, a reflection grating filter made of a fiber, a tap made of a fiber and a phase modulator made of a fiber. SOLUTION: An input wavelength is equally divided to a port 2 and a port 3 by the coupler 10. The phase modulator 12 imparts a small dither signal to the phase of the light from the port 3. A reflector 11A and a reflector 11B returns the one wavelength to the coupler 10 while matching. Both of the two reflected optical powers interfere with each other in the coupler 10 based on their overall phase. The tap 13 samples the interference of the reflected light power and the dither signal. The tap 13 applies the samples of the interference signal and the dither signal to the controller 14. The controller 14 analyzes the dither signal and forms a compensation voltage in the phase modulator 12.

Abstract: In accordance with the invention a multiwavelength optical fiber cross connect is provided with an active all-fiber optical router for multiplexing/demultiplexing. The router is comprised of one electronic component -- a phase controller -- and four fiber components: 1) a fiber directional coupler, 2) a fiber reflective grating filter, 3) a fiber tap, and 4) a fiber phase modulator. The application describes how to make optical routers from these components ranging in complexity from a single wavelength drop router to an N-port, N-wavelength router for add/drop multiplexing. The application also describes how optical wavelength routers can be combined to create optical fiber Cross connect (OXCs), ranging in complexity from 2X2 single wavelength OXCs to NXN, M-wavelength OXCs.
