摘要： An optical switch 1 has a plane waveguide 2 provided with optical waveguide 3, and an actuator structure 5 including a beamlike member 6 supported in a doubly supported manner on the plane waveguide 2. A mirror 10 for shutting out light passing on the optical waveguide 3 is provided in the central region of the beamlike member 6. Interconnecting members 12 extending in the longitudinal direction of the beamlike member 6 are coupled to the both ends of the beamlike member 6. The interconnecting members 12 preliminarily exert a compressive force on the beamlike member 6 so as to deflect the beamlike member 6 with compression stress in an initial state in which the mirror 10 is located at a position where the mirror allows the light passing on the optical waveguide 3 to pass or at a position where the mirror shuts out the light passing on the optical waveguide 3.

摘要： An optical variable attenuator has a planar waveguide, which is provided with optical waveguides forming an input optical line A and an output optical line B. A cantilever is disposed at the upper face of the planar waveguide, whereas a movable mirror for reflecting light passing through the input optical line A toward the output optical line B is secured to the leading end part of the cantilever. An electrode is disposed at the upper face of the planar waveguide. The cantilever and the electrode are connected to each other by way of a voltage source. The voltage source applies a voltage between the cantilever and the electrode, so as to generate an electrostatic force therebetween, which flexes the leading end side of the cantilever toward the electrode. As a consequence, the movable mirror moves toward the electrode.

摘要： An optical signal, which is to become the subject of dispersion compensation, is split by optical combining/splitting unit 2, and each frequency component of the optical signal that is split is reflected by each reflective surface of reflective mirror 40 of reflective means 4 to apply a predetermined phase shift to the respective frequency components. Each reflected frequency component is then combined using optical combining/splitting unit 2, to give dispersion compensated optical signal. Furthermore, in regards to reflective means 4, which is used to apply phase shift to each frequency component of an optical signal, reflective mirror 40 is made a variable movable mirror by reflection position at each reflective surface, which reflects the frequency components, deforming the entire reflective surface. This allows dispersion that is created in an optical signal to be compensated with favorable controllability and high accuracy. As a result, it becomes possible to provide a variable dispersion compensator that presents high precision and controllability of dispersion compensation, and has a miniaturized optical circuit, and an optical transmission system comprising such variable dispersion compensator.
