Faraday rotation of the polarization for a 1550 nm probe beam induced by a pump beam at shorter wavelength is studied in Hg1-xMnxTe semimagnetic semiconductors. Photoinduced rotation decays in a nanosecond timescale and it is related to carrier-induced refractive index saturation. Observed decay is discussed in terms of photoexcited carrier dynamics.

Abstract
Faraday rotation of the polarization for a 1550 nm probe beam induced by a pump beam at shorter wavelength is studied in Hg1-xMnxTe semimagnetic semiconductors. Photoinduced rotation decays in a nanosecond timescale and it is related to carrier-induced refractive index saturation. Observed decay is discussed in terms of photoexcited carrier dynamics.File in questo prodotto:
