Abstract
A Faraday rotator for rotating a plane of polarization of polarized light, said Faraday rotator having an optical element comprising a rod which is comprised of an optically transmitting composition comprising from about 15 wt. % to about 50 wt. % germanium, from about 5 wt. % to about 20 wt. % arsenic, and from about 30 wt. % to about 80 wt. % selenium. This Faraday rotator is especially useful in an optical isolator for preventing feedback of transmitted light waves.
