Final Report Abstract

The major achievements of the project are: 1. Demonstration of the successful 2”-scale wafer-bonding process and the resulting successful metal-metal waveguide fabrication, lasing at 17µm in pulsed mode and delivering up to mW of pulse power. 2. Demonstration of Peltier-cooled THz QCL operation using an externally provided (TU Vienna) QCL chip and in-house designed multi-stage TEC-setup. The major surprise was the inability of the longer wavelength designs as grown to lase.
