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.
