Optical switching in PbSnSe at low temperature

We report the first observation of optical switching in lead chalcogenide semiconductors. In the transmission of pulsed CO 2 laser radiation through n-type Pb 0.98Sn 0.023Se at temperatures between 44 and 72 K, Fabry-Pérot cavity switching was observed. Evidence of both thermal and electronic switch...

Summary:We report the first observation of optical switching in lead chalcogenide semiconductors. In the transmission of pulsed CO 2 laser radiation through n-type Pb 0.98Sn 0.023Se at temperatures between 44 and 72 K, Fabry-Pérot cavity switching was observed. Evidence of both thermal and electronic switching processes was found and electronic switch-down times of ≈ 10 ns indicate a radiative recombination limited minority carrier lifetime.
