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.
