By now it has been nearly twenty years since the pioneering studies at the MIT-Lincoln Laboratories, Lexington, USA, demonstrated the unique capabilities of lead salt tunable diode lasers (TDL) for infrared absorption spectroscopy. The progress in th

Depending on the doping and annealing conditions, as well as the oxygen content, erbium produces a big variety of different centres in silicon. These centres can be distinguished by their fine structure patterns seen both in luminescence and in excit

Room-temperature electroluminescence is obtained from erbium-doped Si diodes for heavily Er- and oxygen-doped material. Such diodes exhibit under reverse bias excitation a characteristic, about 10–20 nm wide emission spectrum which has a striking s

Lasers made of lead salt compounds have proven to be best suited for coverage of the mid-infrared region from 3 to 30 mu m. Nowadays double-heterostructure (DH) lasers are the standard, using as active layers PbEuSSe for the short-wavelength region b
