    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
