Distributed feedback terahertz frequency quantum cascade lasers with dual periodicity gratings
F. Castellano, S. Zanotto, L. H. Li +5
We have developed terahertz frequency quantum cascade lasers that exploit a double-periodicity distributed feedback grating to control the emission frequency and the output beam di…

Room-temperature transverse-electric polarized intersubband electroluminescence from InAs/AlInAs quantum dashes
V. Liverini, L. Nevou, F. Castellano +4
We report the observation of transverse electric polarized electroluminescence from InAs/AlInAs quantum dash quantum cascade structures up to room temperature. The emission is attr…
