    摘要： A tunable optical waveguide chip for optical transforms. Roughly described, the chip includes a planar waveguide having a lens region and a plurality of individually addressable energy applicators distributed transversely across an optical path through the lens region. By individually controlling the energy applied to each of the energy applicators, a desired index of refraction profile can be induced in the lens region transversely across the optical path for performing any of a variety of optical transforms. The device may include an upstream AWG which focus a wavelength de-multiplexed signal on a focal plane within the lens region. The applicators may be thermo-optic or electro-optic, for example.

    摘要： A waveguide optical interferometer which is low in cost, has high reliability, and is independent of polarization, or has a specific polarization dependence. In an optical multiplexer / demultiplexer such as an AWG, or a Mach-Zehnder interferometer, which utilizes interference of a light beam passing through a plurality of optical waveguides of different lengths, all the integrals of the birefringence values of the optical waveguides (which may change or not change along the waveguides) in the longitudinal direction of the waveguides (1703 and 1704) are either made to be equal to each other, or their difference is set to a specific value. Thus, polarization-independent operation or, to the contrary, polarization-selective operation can be realized, only by changing the waveguide widths. For instance, in a Mach-Zehnder interferometer, the integrals of the birefringence values of two waveguides may differ from each other by half the optical wavelength used, thereby realizing a polarization beam splitter.

    摘要： An optical waveguide circuit such as an array waveguide diffraction grating in which the influence of polarization-dependent loss can be suppressed without providing a half-wave plate. A lower clad is formed on a silicon wafer (11). A core having the following waveguide constitution is formed thereon. An input-side slab waveguide (13) is connected to the output side of a plurality of incidence waveguides (12), and a plurality of array waveguides (14) having different lengths are connected side by side to the output side. An output-side slab waveguide (15) is connected to the output side thereof, and a plurality of output waveguides (16) is connected to the output side. The core is clad with upper clad. A plurality of multiplex-inputted incident light beams having different wavelengths are separated for every wavelength and outputted. The clad and the core are made of silica glass. The absolute value |B| of double refraction caused in the optical waveguide circuit is |B| . The relationship between the coefficient of thermal expansion alpha g of the upper clad and the coefficient of thermal expansion alpha s of the silicon wafer is expressed by alpha s-2.0 x 10 .
