Abstract
Summary form only given. To obtain a laser, cladding layers have to be added to the structure, in order to maximize the overlap of the emitted radiation with the active region. To this end, we use a 20 /spl Aring//20 /spl Aring/ InAs/AlSb superlattice where the InAs layers are n doped with Si n = 5 X 10/sup 18/ cm/sup -3/. This type of cladding has already been used in interband cascade lasers.
