Abstract

Hollow core waveguides made of TiO₂–SiO₂ based glasses have been proposed for the IR. A series of TiO₂–SiO₂ based glasses were prepared and their complex refractive indices measured by reflectometry. Using measured refractive indices, we calculated spectral losses of the TiO₂–SiO₂ hollow waveguides. With the waveguides, we can expect efficient transmission of mid-IR light including CO₂ laser light, since refractive indices of the glasses become less than unity and the absorption coefficients become small in the 8–11-μm wavelength range.
