Abstract:

We present an investigation on the electrical, optical, and spectral properties of distributed feedback tapered quantum cascade lasers emitting at 14-15 μm, based on the InAs/AlSb material system. Tapered lasers provide higher power outputs without degrading the beam quality. Devices with different taper angles were tested and compared with conventional ridge waveguide lasers.
