Quantum Well Design for Red-Emitting InGaN LEDs
TS-042441 — The quantum well design is incorporated within a red-emitting InGaN QW LED, an LED type that usually cannot efficiently emit wavelengths larger than blue/green. The LED can be incorporated into a same-material RGB platform for white LEDs, because the well design increases efficiency and decreases indium composition compared to similar wavelength InGaN LEDs.
Blue-emitting InGaN quantum well (QW) LEDs now have 69% external quantum efficiency, but increasing the emitted-wavelength decreases the efficiency significantly. The inversion asymmetry of the InGaN lattice increases the induced strain, which in turn increases the piezoelectric effect. Charge bui…

Technologies for an optical switching engine
TS-015303 — Modifications were made to a White cell and Fourier cell to improve optical switching engines. These improvements include a reduction of cost, elimination of size restrictions, and increase of efficiency.
Today's cutting-edge technology uses electrons to pass information. Tomorrow's technology will use light, through fiber optics, to do the same thing. The joining of current technology with fiber optics is commonly referred to as photonics. Present day research in this field looks at how li…

Efficient Graded III-Nitride Nanowires
TS-014952 — A nanowire that overcomes defect formation normally found in LEDs, leading to higher charge density.
Unlike traditional light bulbs, Light Emitting Diodes (LEDs) use less power, last longer, and contain no environmentally harmful substances. However, LEDs struggle with technical errors, such as lattice mismatch and large resistances. As adoption increases, it is necessary to develop LEDs that are…
