摘要： A DGD compensating apparatus capable of compensating the time varying DGD of each wavelength component in the propagation light. The DGD of each wavelength component in the inputted light is monitored by a DGD monitor, and a polarization splitter splits the inputted light into first polarization light and second polarization light orthogonal to each other. The first polarization light is de-multiplexed by de-multiplexer for each wavelength component, and the de-multiplexed wavelength components in the first polarization light are multiplexed by a multiplexer after being respectively added with delays by an optical delay. The first polarization light in which each wavelength component is added with the associated delay and the second polarization light are combined and thereafter being outputted by a polarization combiner.

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).
