Title
(EN) CONTROLLABLE WAVELENGTH SELECTING OPTICAL CROSS CONNECT
(JA) 制御可能な波長選択光クロスコネクト
Abstract
(EN)

PROBLEM TO BE SOLVED: To attain high speed operation or the like without requiring photoelectric conversion and optoelectronic conversion by allowing a controllable fiber diffraction grating to transmit or reflect an individual channel in a multi- wavelength optical signal so that a channel having prescribed wavelength and allowed to be selected is routed from either one of input ports of a switch to either one of output ports.

SOLUTION: An optical router part 150 in an optical switch 100 includes directional optical transfer devices 101, 102 and distributes multiwavelength input signals I1, I2. An optical combiner part 151 includes directional optical transfer devices 103, 104, combines a multiwavelength optical signal and outputs output signals O1, O2. The devices 103, 104 are respectively connected to output optical fibers 108, 109 to supply the output signals O1, O2. These devices 101 to 104 can directionally transfer or combine optical energy.
