Thermally induced optical bistability in PbTe at room temperature

Thermally induced optical bistability by continuous-wave CO sub(2) laser excitation is obtained for the first time in PbTe. Optical switching of the etalon at T = 300 K is achieved for input powers of tens of milliwatts. A theoretical analysis of the input-output characteristics is presented, where...

Zusammenfassung:	Thermally induced optical bistability by continuous-wave CO sub(2) laser excitation is obtained for the first time in PbTe. Optical switching of the etalon at T = 300 K is achieved for input powers of tens of milliwatts. A theoretical analysis of the input-output characteristics is presented, where the temperature dependence of the free carrier absorption has been accounted for.
