We report the first observation of optical switching in lead chalcogenide semiconductors. In the transmission of pulsed CO2 laser radiation through n-type Pb0.98Sn0.023Se 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. © 1986.
