摘要： An integrated bi-directional transceiver device for multiple wavelength optical signals that has a high level of wavelength isolation at the receivers of the device and low cross-talk of light between an external laser transmitter and the receivers. A WDM planar light wave circuit (PLC) assembly combines high spatial light confinement waveguide structures and a variable thickness dielectric wavelength selective filter (WSF) on the surface of the device to reflect a first wavelength signal and to pass a second wavelength signal. Embodiments of the invention include branching waveguide structures and folded path waveguide assemblies with multiple WSF's.

摘要： Waveguide structures in which light confinement strength varies along the direction of light propagation are described. The waveguides include a core adapted to propagate light along a path defined by the core and a cladding material that at least partially surrounds the core. The core and the cladding material each have a refractive index profile in the direction of light propagation. One or more of the profiles or lateral core dimensions are varied along the direction of light propagation, thereby causing the degree of light confinement to vary in the direction of light propagation. With such structures it is possible to tailor the velocity of the light propagating through the core and the confinement of the light to the core for any given core cross section. The structures may be used, for example, in mode-matching an input or output of a waveguide and in fabricating compact directional couplers.

摘要： A method and apparatus for processing an optical signal in an optical waveguide using a closed loop wavelength dependent active tuning system. A tunable fiber Bragg grating, optical processor and a controller provide feedback control of the central wavelength of the tunable fiber Bragg grating. Changes in wavelength of the processed signal are followed to keep the tunable fiber Bragg grating tuned to a peak wavelength for maximum sensitivity.

摘要： A photosensitive sol-gel film containing an organometallic photosensitizer is deposited on the oxide containing surface layer of a silicon substrate. A pattern of white or ultra violet light incident to the photosensitive sol-gel film results in the unbinding of the photosensitizer from the exposed regions of the sol-gel film. A subsequent succession of first and second heating steps results in, first, the removal of the photo sensitizer constituents from the exposed regions of the sol-gel film and, second, the removal of the organic constituents from the exposed regions, resulting in regions doped with a metal oxide with non linear optical properties, such as semicondutive, etc. properties. Optical switches, couplers, waveguides, splitters, interferometers wavelength division multiplexer, Bragg gratings and more can be fabricated. A glass substrate also may be employed, instead of a silicon, in which case a separate silicon oxide surface layer is unnecessary.

摘要： Processes for fabricating integrated optics devices are provided. According to one process, a photosensitive sol-gel glass material including a volatile photosensitizer is prepared. A film of the sol-gel is then produced on a substrate. The film is then imprinted with an image of an optical device by exposing the photosensitive sol-gel film to light energy patterned in the negative or positive image of the desired device, thereby photolyzing photosensitizer within the exposed portion in proportion to the amount of light energy delivered. The image of the written optical device is then fixed in the exposed film, thereby forming a planar device layer having an embedded optical device. The photoinduced refractive index change between the optical device and the surrounding region is preferably greater than or equal to 0.001. A variety of passive and active integrated optic devices may be fabricated using the disclosed processes and are also described.

摘要： Apparatus for acquiring an image of a specimen comprising a cassette having an optical portion holding a specimen array on a TIR surface and being removably matable to a processing portion having a polarized light beam source and a processing polarization-sensitive portion to image the spatially distributed charges in polarization of the specimen array. In one form the array optical portion comprises a transparent slide having a bottom surface with first and second gratings located to direct polarized light to the TIR surface and to direct light reflected by that (TIR) surface to an imager, respectively. The apparatus may include a flow cell integral with the optical portion as well as means for selecting the direction and wavelength of the polarized light.
