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).

摘要： This invention provides an optical signal processing apparatus capable of size reduction. When signal light with multiple wavelengths &lgr;1 to &lgr;4 is collimated by and output from a fiber collimator, the signal light components with multiple wavelengths &lgr;1 to &lgr;4 are diffracted by a diffraction grating at diffraction angles corresponding to the wavelengths and separated for the respective wavelengths. The separated signal light components of the respective wavelengths are output to spatially different optical paths. The signal light components having the wavelengths &lgr;n are deflected at their optical paths by prisms to increase the optical path interval and then input to fiber collimators.

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： A first optical system (11) has a first beam splitter (211). The first beam splitter (211) splits light arriving through a first optical path (P1) into two light beams, and outputs one light beam to a second optical path (P2) and the other light beam to a third optical path (P3). A second optical system (21) outputs the light output from the first beam splitter (221) to the second optical path (P2) and arriving at the second optical system (21) upon giving the light an intensity change with wavelength dependence and a phase change, and has a second beam splitter (221), first reflecting mirror (223), and second reflecting mirror (222). This makes it possible to provide an optical filter (200) which can realize a characteristic excellent in isolation with a very simple arrangement.

摘要： In a polarized wave interleaver 100, signal light of a first wavelength band Λ1 of polarized light component in a first orientation, which enters an input port 111, proceeds to a first path P1 through a first polarized wave separation element 131. Even after passing through a wavelength filter 140, the polarized light component in the first orientation is maintained as it is. And the light proceeds to a third path P3 through a second polarized wave separation element 132, and is output from a first output port 121. Signal light of a second wavelength band Λ2 of polarized light component in a second orientation, which enters the input port 111, proceeds to a second path P2 through the first polarized wave separation element 131, and is converted to the polarized light component in the first orientation by the wavelength filter 140. And the light proceeds to a fourth path P4 through the second polarized wave separation element 132, and is output from a second output port 122. The wavelength filter 140 includes a first multi-refraction material 141, a second multi-refraction material 142 and a third multi-refraction material 143. The optical thickness of the three multi-refraction materials 141-143 has a predetermined ratio; and the orientation of the C axis falls within a predetermined range.
