Ultra low threshold current THz quantum cascade lasers based on buried strip-waveguides
S. Dhillon, J. Alton, S. Barbieri +5
THz quantum cascade lasers based on a novel buried cavity geometry are demonstrated by combining double-metal waveguides with proton implantation. Devices are realised with emissio…

High-performance planar light-emitting diode
Marco Cecchini, Vincenzo Piazza, Fabio Beltram +5
Planar light-emitting diodes (LEDs) fabricated within a single high-mobility quantum well are demonstrated. Our approach leads to a dramatic reduction of radiative lifetime and jun…
