Spin injection efficiency at metallic interfaces probed by THz emission spectroscopy
Jacques Hawecker, T. H. Dang, Enzo Rongione +12
Terahertz (THz) spin-to-charge conversion has become an increasingly important process for THz pulse generation and as a tool to probe ultrafast spin interactions at magnetic inter…
Ultrasensitive Photoresponse of Graphene Quantum Dot in the Coulomb Blockade Regime to THz Radiation
E. Riccardi, S. Massabeau, F. Valmorra +11
Graphene quantum dots (GQDs) have recently attracted considerable attention, with appealing properties for terahertz (THz) technology. This includes the demonstration of large ther…
Origins and control of the polarization splitting in exciton-polaritons microwires
Ombline Lafont, Vincenzo Ardizzone, Aristide Lemaître +6
We report on the experimental investigation of the polarization-dependent energy splitting in the lower exciton-polariton branches of a 1D microcavity. The splitting observed for t…
Terahertz emission from multiple-microcavity exciton-polariton lasers
Simon Huppert, Ombline Lafont, Emmanuel Baudin +2
Terahertz emission between exciton-polariton branches in semiconductor microcavities is expected to be strongly stimulated in the polariton laser regime, due to the high density of…
Observation of inter-Landau-level quantum coherence in semiconductor quantum wells
K. M. Dani, I. A. Cotoros, J. Wang +4
Using three-pulse four-wave-mixing femtosecond spectroscopy, we excite a non-radiative coherence between the discrete Landau levels of an undoped quantum well and study its dynamic…
Ultrafast dynamics of coherences in the quantum Hall system
K. M. Dani, J. Tignon, M. Breit +3
Using three-pulse four-wave-mixing optical spectroscopy, we study the ultrafast dynamics of the quantum Hall system. We observe striking differences as compared to an undoped syste…
