Abstract
Stable glasses composed of two or more of the oxides of bismuth, lead, gallium, and cadmium have been previously reported as having infrared cut-offs of about 8pm, significantly more transmissive than any other oxide glass. They are yellow, having a lower absorption edge at about 470 nm. Refractive indices are about 2.4 at 0.6μm and 2.2 at 5μm. The material dispersion and cross-over wavelength are favorable for low-loss optical fibers operating near 3μm.Keywords
