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.

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 switch according to this invention has a planar waveguide in which an optical path is formed. A trench is formed in the upper surface of this planar waveguide. A cantilevered movable member is mounted on the planar waveguide. A comb is formed in the end portion of this movable member. A mirror which intercepts light propagating on the optical path is fixed to the end of the movable member. An electrode opposing the movable member is formed on the planar waveguide. A comb is formed in that portion of this electrode, which opposes the comb of the movable member. The movable member and electrode are connected via a voltage source. When this voltage source generates electrostatic force between the movable member and electrode, the movable member bends, and the mirror moves along the bottom surface of the trench accordingly.

摘要： The present invention relates to an AWG type optical multiplexer/demultiplexer having a small size in a state where cross talk is effectively restrained from increasing between adjacent channels. The optical multiplexer/demultiplexer is designed such that, in a power spectrum indicating a wavelength-transmission characteristic concerning an output light component from selected one of output waveguides disposed so as to correspond to respective signals having channel wavelengths set with a predetermined wavelength spacing, an adjacent channel wavelength exists within a wavelength region yielding an output light power lower than that at the channel wavelength corresponding to the selected one by 20 dB or more, whereby the cross talk between adjacent channels occurring as the optical multiplexer/demultiplexer attains a smaller size is effectively suppressed.

摘要： The present invention relates to an optical multiplexer/demultiplexer which ameliorates the deterioration in crosstalk characteristics between adjacent signal channels in a simpler configuration with a better reproducibility. In this optical multiplexer/demultiplexer, a space filled with cladding glass having a size which is at least three times the width or thickness of each channel waveguide is provided between the slab and channel waveguides. This configuration effectively improves the deterioration in crosstalk between adjacent signal channels on a par with the case where the slab and channel waveguides are directly connected to each other.
