    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 the corresponding reflective mirror 30 included in reflective mirror group 3 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 mirror group 3, which is used to apply phase shift to each frequency component of an optical signal, each of the respective plurality of reflective mirrors 30 is made a movable mirror having a movable reflection position that reflects the frequency components. Through this, dispersion that develops in an optical signal may be compensated with favorable controllability and high accuracy. Therefore, the precision and controllability of dispersion compensation will become superior, and realized is a variable dispersion compensator having a miniaturized optical circuit, and an optical transmission system comprising such variable dispersion compensator,

    摘要： The inclination of a reflecting surface of a mirror is adjusted such that light outputted from an input optical fiber is reflected by the mirror so as to be fed into an output optical fiber. The normal direction of the reflecting surface of the mirror vibrates about a predetermined direction at a predetermined frequency. A part of the light propagating through the output optical fiber is taken out by a light-branching part, so as to be received by a photodiode, whereby an electric signal having a value corresponding to thus received quantity of light is outputted from a detection circuit. Whether or not the electric signal includes a component of the predetermined frequency or whether the component is strong or weak is detected, whereby whether or not there is optical coupling from the input optical fiber to the output optical fiber or the extent thereof is determined.

    摘要： The present invention is related to an optical multiplexer/demultiplexer having a structure capable of allowing higher manufacturing tolerance for attainment of improvement in transmission wavelength characteristics. In the optical multiplexer/demultiplexer, a free propagation area for improvement in the transmission wavelength characteristics is provided between an input waveguide and a first slab waveguide. This free propagation area has a first portion increasing its width from the input waveguide toward the first slab waveguide and a second portion having the width larger than that of the input waveguide. The first portion once broadens an electric field strength distribution of light traveling from the input waveguide to the first slab waveguide, and the second portion restricts the broadening on the other hand. This makes change of the electric field strength distribution less susceptible to change of the waveguide width, so as to relax required accuracy for microprocessing as a result.
