Abstract

The novel unipolar laser resembles a quantum cascade laser but utilizes radiative transitions between upper and lower minibands of superlattices, with injection of charge carriers from the lower miniband into the upper miniband of the adjacent downstream superlattice facilitated by a multilayer injector region. The lasing wavelength is typically in the mid-infrared, selectable by choice of the superlattice parameters. The novel laser is potentially well suited for high power operation, since it utilizes carrier transport in minibands, as opposed to tunneling between discrete energy states.
