Abstract

We present high power mid‐infrared surface‐emitting single mode GaAs‐based quantum cascade lasers (QCLs). By using an air‐AlGaAs waveguide combined with second‐order distributed feedback processing, we obtained optical output, via the surface, above 3W. Surface‐normal dual‐lobe light emission exceeds the emission from one as‐cleaved facet by a factor of six. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

We present measurement results on high-power low-threshold quantum cascade-distributed feedback lasers emitting infrared radiation at 10:16 m. A lateral current injection scheme allowed the use of a strongly coupled surface grating without metal coverage and epitaxial re-growth. Although this design
