    摘要： An integrated optical microstructure includes a substrate carrying an optical waveguide and supporting a medium disposed to receive optical energy from the waveguide. The medium includes an optical re-radiator such as a phosphor, which reradiates optical energy in response to optical energy received from the waveguide. The structure further includes a reflector disposed to redirect some of the input optical energy emanating from the medium back into the medium, to achieve spatial confinement of the input light delivered by the input waveguide. The structure can thereby increase the efficiency of the light conversion processes of re-radiating materials. An aperture in the reflector permits optical energy emitted by the re-radiator to emerge from the structure and to propagate in a preferred direction, such as toward a viewer or sensor. The structure is useful for increasing the brightness of various kinds of small emissive elements which are excited by light delivered from an integrated optical waveguide, including pixels in an information display.

    摘要： Method for optical energy transfer and energy guidance uses an electric field to control energy propagation using a class of poled structures in solid material. The poled structures, which may form gratings in thin film or bulk configurations, may be combined with waveguide structures. Electric fields are applied to the poled structures to control routing of optical energy. Techniques include frequency-selective switchable- and adjustable-tunable reflection, splitting, directional coupling, frequency-tunable switching and efficient beam combining, as well as polarized beam combining. Adjustable tunability is obtained by a poled structure which produces a spatial gradient in a variable index of refraction along an axis in the presence of a variable electric field. In one embodiment, the present invention is a method of switching a grating which consists of a poled material with an alternating domain structure of specific period. When an electric field is applied across the periodic structure, a Bragg grating is formed by the electro-optic effect, reflecting optical radiation with a certain bandwidth around a center wavelength. The grating may be used by itself, or in combination with other gratings to form integrated structures in a ferroelectric crystal. Specifically of interest is an method of using an integrated structure in which one or more optical waveguides interact with one or more periodic structures to form a wavelength selective integrated optic modulator, switch, or feedback element.

    摘要： An integrated isolator array is provided having a plurality of waveguides fabricated in a planar optical substrate, each waveguide having input and output sections. An isolator subassembly is received within a transverse trench formed in the substrate between the input and output sections such that it intersects the optical paths of the waveguides. The isolator subassembly, which may consist of layers of Faraday rotator material sandwiched between layers of birefringent crystal material, permits the forward passage of light from the input sections to the output sections of the waveguides while preventing the backward passage of light from the output to the input sections. Each waveguide input section is preferably adapted with a mode-expanding input taper to collimate light propagating through the waveguide. Similarly, each output section is preferably adapted with a mode-reducing output taper to reduce the mode size of forward-traveling light to match that of an output fiber, as well as to collimate light traveling backward within the output section.

    摘要： A redundant optical connection system is manufactured in specially prepared form to allow optical connections to be made at a later step. In response to information specifying which of the optical sources are functional, further structure may be activated or introduced into the connection system which guides optical energy to optical outputs from only those of the sources that are functional. In one aspect of the invention, the preliminary form includes primary guiding structures coupling each of a plurality of primary optical sources to a respective application structure, and a secondary guiding structure coupled to a secondary optical source and terminating without yet coupling to any application structure. If the information indicates that one of the primary optical sources is non-functional, then structure can be added or activated which transfers optical energy from the secondary guiding structure into the primary guiding structure corresponding to the non-functional source. In another aspect of the invention, the preliminary form includes a material having N optical sources and more than N output guiding structures. A gap region is provided in the material between the outputs of the optical sources and the inputs of the output guiding structures. Additional guiding structures are later formed or activated in response to the information, to guide optical energy to the inputs of the output guiding structures from only functional ones of the optical sources.
