Title: Optical panel system including stackable waveguides

Abstract

An optical panel system including stackable waveguides is provided. The optical panel system displays a projected light image and comprises a plurality of planar optical waveguides in a stacked state. The optical panel system further comprises a support system that aligns and supports the waveguides in the stacked state. In one embodiment, the support system comprises at least one rod, wherein each waveguide contains at least one hole, and wherein each rod is positioned through a corresponding hole in each waveguide. In another embodiment, the support system comprises at least two opposing edge structures having the waveguides positioned therebetween, wherein each opposing edge structure contains a mating surface, wherein opposite edges of each waveguide contain mating surfaces which are complementary to the mating surfaces of the opposing edge structures, and wherein each mating surface of the opposing edge structures engages a corresponding complementary mating surface of the opposite edges of each waveguide.

  • An optical panel is disclosed. A plurality of stacked planar optical waveguides are used to guide light from an inlet face to an outlet face of an optical panel. Each of the optical waveguides comprises a planar sheet of core material having a central plane. The core material has an index of refraction which decreases as the distance from the central plane increases. The decrease in the index of refraction occurs gradually and continuously.

  • Quantum communication transmitters include beacon lasers that transmit a beacon optical signal in a predetermined state of polarization such as one of the states of polarization of a quantum communication basis. Changes in the beacon polarization are detected at a receiver, and a retarder is adjusted so that the states of polarization in a received quantum communication optical signal are matched to basis polarizations. The beacon and QC signals can be at different wavelengths so that the beacon does not interfere with detection and decoding of the QC optical signal.
  • This patent describes an optical system. It comprises at least one wavelength-tunable source of laser radiation, the source including a semiconductor laser comprising an active layer sandwiched between first and second layers of material having a lower refractive index than that of the active layer, the active layer having a composition which includes III-V compound semiconductor material; and at least one photodetector, capable of optical communication with the source, characterized in that the active layer includes at least one layer of n-type dopant and at least one layer of p-type dopant, and the source further includes means for optically and/ormore » electrically, nonuniformly pumping the active layer, the degree of nonuniformity being such that the resulting, average excitation level in at least a first region of the active layer is at least ten percent higher than that in a second region of the active layer. The average excitation level in the second region being less than the threshold level needed to achieve stimulated emission in the second region.« less
