ABSTRACT
This paper presents recent developments in the field of lead-salt light-emitting devices, having enormous applications in mid-infrared (MIR) opto-electronics. For the first time, achievement of an electrically excited edge-emitting QW laser on PbSnSe substrate is described. Novel fabrications of freestanding microstructures in the form of rod, tube and pillar, having vast applications in MEMS and NEMS, are reported.
