摘要： An nxn thermo-optical switch (40) comprises a first array (50) of n waveguides (51 to 58) and a second array (60) or waveguides (61 to 68) crossing the waveguides of the first array. The waveguides may be formed from various materials such as polymers. The angle theta defined by the intersection between waveguides of the first array (50) and with the second array (60) is between two degrees (2 DEG ) and six degrees (6 DEG ). An electrode heater (80) is disposed adjacent to each intersection (70) of the first array of waveguides (50) with the second array of waveguides (60). Heating of both the cladding material and portions of the associated waveguides at each intersection (70) changes the refractive index such that total internal reflection may occur. A communication system includes a switching center comprising a plurality of n n thermo-optical switches (40), a plurality of wavelength division demultiplexers and a plurality of variable optical attenuators.

摘要： A switching element formed with at least a pair of intersecting channel optical waveguide paths. A polymer switching element is formed across the waveguide paths at the point of intersection. The offstate refractive index of the polymer switching element substantially matches the refractive index of the waveguide paths. Optical switching between the waveguides is achieved by changing the refractive index of the polymer switching element by applying heat to the polymer switching element. The heat can be applied by a thin-film heater formed on top of the polymer switching element at the switch intersection. The application of heat causes total internal reflection in the polymer switching element to divert light from the first or input waveguide path to the second or cross-state output waveguide path.

摘要： Charged particles (21) suspended in a medium (20) such as Fluorinert Electronic Liquid are used to electrophoretically control total internal reflection (TIR) at a retro-reflective surface formed on a high refractive index material. Prismatic structures (35, 32, 81) redirect ambient light from an overhead light source toward a display image and then from the image to the region in front of the image, yielding a high contrast reflective display. A transparent planar waveguide (36) front lights the display with sequential flashes of red, blue and green light to generate a full colour display. TIR can also be controlled at retro-reflective surfaces by means of a vapour-liquid phase transition, or by changing the absorption coefficient of a material using electrical, chemical and/or electrochemical methods.

摘要： Programmable waveguide devices and associated methods are described. The waveguide devices can be programmed to operate as an optical switch, an optical attenuator, an interferometer, a mode transformer, an optical computer or other devices. An example programmable waveguide device includes a grid where an electro-optic material is positioned between a plurality of top and bottom electrodes that each form a pair of electrodes as part of a grid element. The programmable waveguide device also includes input ports and output ports; the latter output one or more beams produced from the one or more input beams after propagation through the grid. Each grid element can receive a voltage across the electro-optic material of the grid element, which exhibits different indices of refraction depending on the voltage. The grid elements are thus configurable to produce regions within the grid with varying indices of refraction based on the voltage.

摘要： An optical device includes a first waveguide, having parallel first and second faces and parallel third and fourth faces forming a rectangular cross-section, that guides light by four-fold internal reflection and is associated with a coupling-out configuration that couples light out of the first waveguide into a second waveguide. The first or second face is subdivided into first and second regions having different optical characteristics. The optical device also includes a coupling-in configuration having a surface that transmits light into the first waveguide. The surface is deployed in association with a portion of the third or fourth face adjoining the second region such that an edge associated with the surface trims an input collimated image in a first dimension, and a boundary between the first and second regions trims the input collimated image in a second dimension to produce a trimmed collimated image that advances by four-fold internal reflection.

摘要： A brightness enhancing structure for a reflective display incorporates a transparent sheet having an inward hemispherical surface, a backplane electrode, an apertured membrane between the hemispherical surface and the backplane electrode, and a light reflecting electrode on an outward side of the membrane. A voltage source connected between the electrodes is switchable to apply a first voltage to move the particles inwardly through the apertured membrane toward the backplane electrode, and a second voltage to move the particles outwardly through the apertured membrane toward the light reflecting electrode. Movement of the particles toward the light reflecting electrode frustrates total internal reflection of light rays at the hemispherical surface. Movement of the particles toward the backplane electrode permits total internal reflection of light rays at the hemispherical surface, and outward reflection from the light reflecting electrode toward the hemispherical surface of light rays which pass inwardly through the hemispherical surface.
