Direct observation of the excitonic ac Stark splitting in a semiconductor quantum well
Michele Saba,Francesco Quochi,Cristiano Ciuti,Denis Martin,Jl Staehli,Benoit Deveaud,A. Mura,G. Bongiovanni +7 more
TL;DR: In this article, the excitonic ac Stark shift in quantum wells was investigated and it was shown that the coherent exciton light coupling in semiconductors can be strong enough to survive the fast dephasing, and therefore an efficient ultrafast manipulation of the exciton absorption in the coherent transient is possible.
Journal ArticleDOI
Time resolved spectroscopy of electron decay in coupled quantum wells—observation of relaxation induced slow-down
TL;DR: In this article, the decay rate of symmetric coupled quantum wells through a potential barrier to a continuum is studied using time resolved optical spectroscopy, and it is shown that at the limit of a thin barrier, the energy splitting between the electron levels disappears.
Journal ArticleDOI
Many-Body Interaction Evidenced through Exciton{Trion{Electron Correlated Dynamics
TL;DR: In this article, the authors investigated the many-body interactions in CdTe modulation-doped quantum wells and found that the nonlinearities induced by trions differ from those induced by excitons and moreover they are mutually correlated.
Proceedings ArticleDOI
The excitonic ac Stark splitting in quantum wells
Michele Saba,Francesco Quochi,Cristiano Ciuti,Denis Martin,Jl Staehli,Benoit Deveaud,G. Bongiovanni,A. Mura +7 more
TL;DR: In this article, the authors report the evolution of the absorption spectrum of a specially designed single InGaAs quantum as well as a function of the growing excitation density, provided by a pulsed Ti:sapphire laser.
Journal ArticleDOI
Temperature dependence of electronic vertical transport in short period GaAsAlGaAs superlattices
TL;DR: In this paper, the vertical transport in superlattices and AlGuAs ternary alloys was studied using time-resolved photoluminescence, and the electron diffusion coefficients were shown to be equivalent in small period SL's and AlGaAs.
