Abstract

The light-by-light control of the polarization state of an intense optical beam is a central issue in many applications requiring fast nonreciprocal operation. Recent studies have shown that semimagnetic semiconductors like Cd_1−xMn_xTe, exhibit giant photoinduced Faraday rotations (PFR), several tens of degrees, with moderate static magnetic field and light intensities and are promising candidates for implementation in such applications.¹
