Active mode locking of quantum cascade lasers operating in external ring cavity
D. G. Revin, M. Hemingway, Y. Wang +2
Stable ultrashort light pulses and frequency combs generated by mode-locked lasers have many important applications including high-resolution spectroscopy, fast chemical detection…
Artefacts in geometric phase analysis of compound materials
Jonathan J. P. Petersa, Richard Beanland, Marin Alexe +4
The geometric phase analysis (GPA) algorithm is known as a robust and straightforward technique that can be used to measure lattice strains in high resolution transmission electron…
Intersublevel Polaron Dephasing in Self-Assembled Quantum Dots
E. A. Zibik, T. Grange, B. A. Carpenter +9
Polaron dephasing processes are investigated in InAs/GaAs dots using far-infrared transient four wave mixing (FWM) spectroscopy. We observe an oscillatory behaviour in the FWM sign…
Fingerprints of spatial charge transfer in Quantum Cascade Lasers
R. Nelander, A. Wacker, M. F. Pereira +7
We show that mid infrared transmission spectroscopy of a quantum cascade laser provides clear cut information on changes in charge location at different bias. Theoretical simulatio…
