Anoex and Kyma Collaborate to Reduce Cost of Blue Lasers and LEDs
Aonex Technologies Inc. of Pasadena, Calif., a developer of substrates that reduce the production cost of devices such as blue LEDs and high-efficiency solar cells, will work with Kyma Technologies Inc. to develop materials to reduce the cost of gallium nitride (GaN)-based devices such as blue laser diodes and blue LEDs, it was announced today. Kyma, of Raleigh, N.C., was spun out of North Carolina State University in 1998 to develop GaN substrate materials for nitride semiconductor device applications. Anoex is a subsidiary of Arrowhead Research Corp., a nanotechnology company based in Pasadena. Blue laser diodes are used in HD-DVD and Blu-Ray DVD players; blue LEDs are used as back lights in cell phones and in other solid-state lighting applications. Because they are more energy efficient and last much longer, blue LEDs are expected to one day replace conventional incandescent and fluorescent lights. Under the agreement, Aonex will provide Kyma with access to its proprietary wafer technology, A-Sapph, which Kyma will use to produce large-area wafers used in manufacturing GaN devices. The large-area wafers could dramatically reduce the cost of GaN devices by helping to increase the number of chips per wafer and the number of wafers produced, the companies said.
- Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
- The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
- The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
- A cross-sectional slice cut from an ingot of either single-crystal, fused, polycrystalline or amorphous material that has refined surfaces either lapped or polished. Wafers are used either as substrates for electronic device manufacturing or as optics. Typically, they are made of silicon, quartz, gallium arsenide or indium phosphide.
