Other key benefits provided by the SiVARA[R] technology include the production of a silica glass
which does not foam or produce bubbles when subject to temperatures exceeding 1700 degrees C.
Using an innovative high-pressure chemical-deposition technique developed by Justin Sparks, a graduate student in the Department of Chemistry, Badding and his team deposited zinc selenide waveguiding cores inside of silica glass
capillaries to form the new class of optical fibers.
Lawandy suspects that the process may involve molecular oxygen and defects formed by the introduction of germanium atoms into silica glass
Their high porosity means their thermal conductivity is about 100 times less than that of fully dense silica glass
, paving the way for use in superinsulating spacers in windows and in shields to trap solar energy.
Concentric silica cylinders with high organic content surround an inner core of high-purity silica glass
, a structure similar to industrial optical fiber, in which layers of glass cladding surround a glass core of slightly different composition.
Another of its main applications is in the plasma deposition of fused silica glass
as a low-k dielectric insulating film between adjacent metal lines.
In common with standard optical transmission fiber made by the MCVD process, SPI's specialty fiber starts life as a hollow cylindrical tube of silica glass
about one metre in length.
The increasing customer interest in fiber lasers and amplifiers operating at eye safe wavelengths has encouraged us to introduce the first in a new generation of highly efficient Tm-doped double-clad fibers where the silica glass
composition has been carefully optimized for efficient operation at the important 2 um wavelength range," says Adrian Carter, Chief Technology Officer of Nufern.
The company has developed the only commercial manufacturing process capable of producing the full complement of active and passive silica glass
materials used to produce optical amplifiers, waveguide lasers and passive planar waveguides.
Polymicro Technologies, founded in 1984, manufactures and distributes silica glass
capillary tubing and accessories, specialty optical fibers, precision fused silica pieces, assemblies, and cables both domestically and internationally.
subsidiary of IXOS SOFTWARE AG (Nasdaq:XOSY)(NEUER MARKT:XOS), a worldwide leading provider of solutions for the management of eBusiness documents in inter-enterprise system environments, announced today that Heraeus-Amersil, North America's leading supplier of silica glass
and fabricated fused quartz, has realized significant time and cost savings with its implementation of IXOS-eCONtext.
Corning Incorporated (NYSE:GLW) today announced that its HPFS(R) fused silica glass
material is being studied by NASA as part of the Materials International Space Station Experiment (MISSE).
