Electro- And Magneto-Optic Effects In Heavy Metal Oxide Glasses

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.
