Accent Optical Technologies of Bend, Ore., a supplier of lattice engineering and photolithography process control tools, announced that Sigm Plus of Moscow, a manufacturer of III-V epitaxial wafers, has placed an order for an RPMSigma photoluminescence mapping system, to used to support manufacturing of GaAs and InP-based epitaxial materials for optoelectronic applications, including laser diodes and LEDs. . . . According to a report by Norwalk, Conn.-based industry researcher Business Communications Company Inc., the total worldwide revenues for fiber optic sensors, a by-product of optical fiber research and development, are projected to increase from the current $288.1 million to $304.3 million in 2006 and will reach $370 million by 2011. Optical fiber sensors are used in telecommunications, medicine, defense and aerospace applications and can be used to measure temperature, pressure, humidity, acceleration and strain. Researchers say the moderate growth rate reflects the challenges facing the market over the next five years, with high cost being a dominant factor.
- optical fiber
- A thin filament of drawn or extruded glass or plastic having a central core and a cladding of lower index material to promote total internal reflection (TIR). It may be used singly to transmit pulsed optical signals (communications fiber) or in bundles to transmit light or images.
- A lithographic technique using an image produced by photography for printing on a print-nonprint, sectioned surface.
- 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.
