Advisory Notes on Optical Isolators for Infrared Wavelengths

June 3, 2014

“It’s the IR that makes isolators difficult.” An Optical Isolator consists of a Faraday Rotator and two Polarizers, all contained in a Body. A Faraday Rotator consists of a Magneto-Optic Material mounted in a magnetic field. (Request separate paper on the Operation of an Optical Isolator). The Magneto-Optic Material must have: low absorption at the […]
