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).

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.

摘要： Light output from the distal end of an optical fiber collimator is input to a first diffraction grating formed on a first surface of a transparent member, and diffracted by the first diffraction grating at angles corresponding to wavelengths, and thus wavelength-branched. The light components of the respective wavelengths branched by the first diffraction grating and having propagated through the transparent member, are diffracted by a second diffraction grating formed on a second surface of the transparent member, and output from the transparent member. Each of the light components of the respective wavelengths, which are diffracted by the second diffraction grating and output from the transparent member, is input to the distal end of a corresponding one of optical fiber collimators, focused, and propagates through the optical fiber.
