    摘要： An AWG is provided which realizes high wavelength isolation at low cost. To achieve this, Bragg gratings which produce refractive index modulation of a waveguide are formed at even spacing for each of the respective waveguides of an input/output waveguide (22), being a multi-core port, which demultiplexes wavelength multiplexed light which is input from an input/output waveguide (21), being a single core port, for each of respective wavelength components. The central wavelength of the Bragg grating is adjusted so as to be on the short wavelength side of the side lobe of the wavelength component branched to the respective waveguides.

    摘要： In accordance with the invention glass waveguide devices are provided with enhanced temperature stability by incorporating within appropriate lengths of the waveguides a transparent compensating material having a refractive index variation with temperature that differs substantially from that of the waveguide. The compensating material can be a non-glass material, such as a liquid, driven into the glass by heat and pressure. In a preferred embodiment, D 2 O is incorporated into waveguides for optical communications. The D 2 O is transparent to the preferred communications wavelengths centered at about 1.55 µm and has a dn/dT opposite in polarity to the dn/dT of glass. The resulting structure exhibits enhanced temperature stability with reduced magnitude of dn/dT. The technique is particularly useful in devices based on interference between multiple waveguides, as it is not necessary to reduce dn/dT to zero in the respective waveguides. It suffices to compensate the differences. Such compensation can be achieved by compensating materials having dn/dT of either the same polarity as the dn/dT of the waveguides or the opposite polarity. Preferred embodiments include routers, Fourier filters and Bragg filters. In single waveguide devices such as gratings, compensating materials of opposite polarity can substantially enhance the temperature stability.

    摘要： An optical wavelength multiplexing/de-multiplexing circuit having a low loss and a flat transmission spectrum is provided. The optical wavelength multiplexing/de-multiplexing circuit compensates a temperature dependence of a center transmission wavelength which remains in an athermal AWG, and has an excellent accuracy of the center transmission wavelength in a whole operating temperature range or has a comparatively wide operable temperature range. Focusing on the fact that a center transmission wavelength of an MZI-synchronized AWG is approximately an average of a transmission wavelength of the MZI and the center transmission wavelength of the AWG, the temperature dependence of the transmission wavelength in the athermal MZI is modulated and set so as to cancel the temperature dependence of the center wavelength which remains in the athermal AWG. The present invention focuses particularly on an optical coupler in the MZI and modulates the temperature dependence of the transmission wavelength in the MZI by providing the optical coupler itself with a mechanism which changes a phase difference between two outputs by temperature.
