Abstract: Novel backlighting units (BLU) for use with LCD panel are disclosed. Such BLUs have direct lighting configuration utilizing blue LED as light source and have quantum dots (QDs) integrated into the architecture of the BLU thus forming thin BLUs that efficiently convert the blue source light into white light while achieving enhanced uniformity in brightness of the white light.

Abstract: A light extraction apparatus includes a flexible substrate, an OLED supported by the flexible substrate, a flexible barrier film, a tapered reflector, and an index-matching layer. The tapered reflector includes at least one side surface, a top surface coupled to the flexible barrier film, and a bottom surface. The top surface is larger in surface area than the bottom surface. The index-matching layer is coupled between a top surface of the OLED and the bottom surface of the tapered reflector. Light emitted from the top surface of the OLED passes through the index-matching layer and into the tapered reflector. The at least one side surface of the tapered reflector includes a slope to redirect the light by reflection into an escape cone and out of the top surface of the tapered reflector.

Abstract: In embodiments, a mode selective optical fiber coupler may include a first propagation waveguide and a second propagation waveguide joined along a coupling length L. The first propagation waveguide and the second propagation waveguide may be tapered from an input face and an output face of the coupler to a midpoint of the coupler. An LP01 mode of an optical signal with a wavelength of 800-950 nm coupled into the first propagation waveguide propagates through the first propagation waveguide and is emitted from the first propagation waveguide. An LP01 loss of the coupler at the output face is less than 1.0 dB. An LP11 mode of the optical signal coupled into the first propagation waveguide is cross-coupled to the second propagation waveguide and is emitted from the second propagation waveguide. An LP11 loss of the coupler at the output face is less than 1.5 dB.
