摘要： The present invention relates a variable optical multiplexer/demultiplexer which can be made smaller and can restrain characteristics from deteriorating. The optical multiplexer/demultiplexer comprises a first optical system, a wavelength branching device, a second optical system, and an optical path changing part. The optical multiplexer/demultiplexer has a plurality of input/output ports, and the first optical system, the wavelength branching device, and the second optical system are disposed between the ports and the optical path changing part. When light is fed into any of the ports, individual wavelength components included in the light are outputted from any of the ports. The optical path changing part inputs the wavelength components condensed by the second optical system, and output the wavelength components to an output optical path which is parallel to but not on the same line as the input optical paths of the wavelength components.

摘要： In an incoming path, light fed to an input port is demultiplexed by a wavelength demultiplexer in terms of wavelength, converged by a first light-converging optical system, reflected by a first reflecting mirror, turned into parallel light by the first light-converging optical system, and multiplexed by the wavelength demultiplexer, so as to be fed to a reflecting surface of a rectangular reflecting mirror. In an outgoing path, the light reflected by the rectangular reflecting mirror is demultiplexed by the wavelength demultiplexer in terms of wavelengths, converged by the first light-converging optical system, reflected by the first reflecting mirror, turned into parallel light by the first light-converging optical system, and multiplexed by the wavelength demultiplexer, so as to be fed to an output port. An image of each wavelength light component reflected by the first reflecting mirror is inverted between the incoming and outgoing paths.

摘要： An optical filter has a first long-period grating and a second long-period grating formed in a unitary optical fiber. A difference is not less than 100 nm between a wavelength at which optical coupling is maximum between core-mode light and cladding-mode light of a predetermined mode number in the first long-period grating and a wavelength at which optical coupling is maximum between core-mode light and cladding-mode light of the same mode number as the cladding-mode light of the predetermined mode number, in the second long-period grating. This optical filter can be constructed in compact size and can readily implement a desired transmission characteristic.
