Abstract
Quantum cascade (QC) lasers based on interband transitions in superlattices are described. These devices, which have potential for very-high peak powers due to the large current carrying capabilities associated with transport in wide minibands, have intrinsic rather than designed population inversion. New QC superlattice (SL) lasers with low threshold based on undoped SLs and QC SL lasers operating simultaneously at two very different wavelengths are studied. Recent results on QC microlasers with `chaotic resonators' obtained by deforming the circular shape of a whispering gallery cylinder laser into a quadropolar shape are also presented.
