Abstract: A Faraday rotator is formed of a class of semiconductor materials of low free carrier density wherein, in the presence of a suitable magnetic field, interband transition Faraday rotation is opposite in sign from free carrier effect Faraday rotation and interband transition Faraday rotation predominates over free carrier effect Faraday rotation such that net Faraday rotation can remain nearly unchanged over broad IR spectral regions where the short wavelength limit is typically near the bandgap absorption. Thus, the class of semiconductors meeting these conditions can function as high performance broadband optical isolators in the infrared. Suitable materials include InAs of suitable purity.
