TiO(2)-SiO(2) based glasses for infrared hollow waveguides
Abstract:
Hollow core waveguides made of TiO(2)-SiO(2) based glasses have been proposed for the IR. A series of TiO(2)-SiO(2) based glasses were prepared and their complex refractive indices measured by reflectometry. Using measured refractive indices, we calculated spectral losses of the TiO(2)-SiO(2) hollow waveguides. With the waveguides, we can expect efficient transmission of mid-IR light including CO(2) laser light, since refractive indices of the glasses become less than unity and the absorption coefficients become small in the 8-11-microm wavelength range.

Among the sp, sp2, and sp3 hybridized orbitals, sp orbitals have the maximum s character (50%). Consequently, the electrons are held more closely to the nucleus, resulting in stronger and shorter C–H bonds that stretch at a...
