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 present invention relates to an optical multiplexer/demultiplexer. In the multiplexer/demultiplexer, a first grating receives to diffract a multi-wavelength light signal from a first port into light signals with different wavelengths. A second grating diffracts these light signals towards second ports. The second grating is disposed parallel with the first grating. The second grating has the same grating interval and grating direction as the first grating. The light signals diffracted by the second grating travel parallel with each other. Therefore, the light signals can efficiently enter the second ports without sophisticated lens design and adjustment of the optical system.

摘要： An optical signal processing apparatus has a diffraction grating element, first condenser lens, Faraday rotation elements, polarization beam splitter, λ/2 plate, second condenser lens, third condenser lens, and diffraction grating element. The magnitude of a magnetic field of each of the Faraday rotation elements is controlled on the basis of an externally input control signal. The rotation angle of the plane of polarization of signal light is set to 0 or λ/2 in accordance with the magnitude of the magnetic field. Each Faraday rotation element receives signal light having wavelengths λ1 to λ4, which has arrived from the first condenser lens, and outputs the signal light as a polarized light component in the first azimuth (parallel to the z-axis direction) or second azimuth (parallel to the y-axis direction).
