Abstract :
We report the performance of 3.5 THz quantum cascade lasers in which the laser cavities are formed by wet chemical etching and show that laser ridges can be obtained using angled facets. This opens up the possibility of monolithic integration of quantum cascade lasers into terahertz circuits.
