Microwave modulation of terahertz quantum cascade lasers : a transmission-line approach

Wilfried Maineult, Lu Ding, Pierre Gellie, Pascal Filloux, Carlo Sirtori, Stefano Barbieri, Tahsin Akalin, Jean-Francois Lampin, Isabelle Sagnes, Harvey E. Beere, David Ritchie

We report on microwave impedance measurements of metal-metal ridge-waveguide terahertz quantum cascade lasers. Experimental data, recorded at 4 K in the 100 MHz–55 GHz range, are well reproduced by distributed-parameter transmission-line simulations, showing that the modulation cutoff is limited by...

Optically active defects in an InAsP/InP quantum well monolithically grown on SrTiO3(001)

Jinquan Cheng, Thomas Aviles, Ahiram El Akra, C. Bru-Chevallier, Ludovic Largeau, Gilles Patriarche, Philippe Regreny, A. Benamrouche, Y. Robach, Guy Hollinger, Guillaume Saint-Girons

The optical properties of an InAsP/InP quantum well grown on a SrTiO3(001) substrate are analyzed. At 13 K, the photoluminescence yield of the well is comparable to that of a reference well grown on an InP substrate. Increasing the temperature leads to the activation of nonradiative mechanisms for...
