  • Patent number: 7653109
    Abstract: An optical assembly, such as a multiple output diode laser pump source for EDFAs, is formed by pressing an optical array emitter chip against a standoff structure protruding from a submount such that the emitter chip deforms to match the curvature of the standoff structure. An IO chip is also juxtaposed against the standoff structure such that its optical receivers can receive optical energy from the emitter chip. The IO chip can provide various optical functions, and then provide an optical array output for coupling into an optical fiber array. The standoff structure preferably contacts the emitter chip over an aggregate contact area much smaller than the area by which the emitter chip overlaps the submount. The materials used for bonding the emitter chip and the IO chip to the submount are disposed in the recesses between standoffs and not on the contact surfaces of the standoff structure.

  • Patent number: 6522794
    Abstract: A flat panel display is based on a new switching technology for routing laser light among a set of optical waveguides and coupling that light toward the viewer. The switching technology is based on poled electro-optical structures. The display technology is versatile enough to cover application areas spanning the range from miniature high resolution computer displays to large screen displays for high definition television formats. The invention combines the high brightness and power efficiency inherent in visible semiconductor diode laser sources with a new waveguide electro-optical switching technology to form a dense two-dimensional addressable array of high brightness light emissive pixels.

  • Publication number: 20020003928
    Abstract: 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 re-radiates 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.

  • Patent number: 5911018
    Abstract: An extremely low-loss optical switch element includes a first waveguide segment having first and second regions longitudinally-adjacent with each other and having an index of refraction difference which is greater when the switch element is in an "on" state than when it is in an "off" state. The two regions have a common boundary which is oriented at an angle in the first waveguide so as to redirect optical energy through total internal reflection when the switch element is in the "on" state. The switch element further includes a second waveguide segment spaced from the first waveguide segment and disposed and oriented to guide optical energy redirected from the first waveguide segment when the switch element is in the "on" state.

  • Patent number: 5852688
    Abstract: 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.

  • Patent number: 5781670
    Abstract: Optical energy transfer devices and energy guiding devices use an electric field to control energy propagation using a class of poled structures in solid material in channel dropping filter and splitter applications. The poled structures, which may form gratings in thin film or bulk configurations, may be combined with waveguide structures. Electric fields applied to the poled structures control routing of optical energy. In a particular embodiment, an electrode confronts a solid material and bridges at least two elements of a grating disposed transverse of two waveguide segments and overlaps evanescent fields of optical energy in one of the waveguide segments. A switchable grating consists of a poled material with an alternating domain structure of specific period. In a further embodiment there may be an optically active cladding between a grating and a waveguide. Additional electrodes may be provided for independent tuning of the cladding and the grating structure.
