Recently lead salts quantum well lasers which exhibit strong quantum optical effects, have been used to fabricate infrared diode lasers with wide single-mode tunability, low waste heat generation and large spectral coverage up to about 10 µm. Based on the energy dependent effective mass method, a theoretical model was developed to study the effects of band non parabolicty and temperature on the tunability of IV-VI PbSe/Pb0.934 Sr0.066 Se laser system. This study will show the effects of temperature as a function of well width on the emitted wavelength. Moreover, it will be shown that the effects of non parabolicity on the energy levels can’t be ignored in the nano range well width.
Key words: Breath analysis, infrared, lead salts, non-parabolicity, quantum well lasers, ,
