Abstract
Quantum cascade lasers operating at a maximum wavelength of 21.5 μm were analyzed. The waveguide design consists of a surface-plasmon guide on top and 1.5 μm of InGaAs n-doped up to 7×1016 cm-3 on the bottom to achieve dielectric confinement. The injectors were designed to avoid tunneling of carriers to higher energy states. The lasers can be used in THz imaging and spectroscopy.
