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 cadmium, zinc, and tellurium, and preferably from about 30 wt. % to about 48 wt. % cadmium, from about 2 wt. % to about 20 wt. % zinc, and about 50 wt. % tellurium. This Faraday rotator is especially useful an optical isolator for preventing feedback of transmitted light waves.
