Proceedings ArticleDOI
Ultrafast Dynamics and Modelling of Semiconductor Optical Amplifiers for WDM Applications
TL;DR: In this article, the cross gain dynamics of the amplifiers are investigated and the results of the experiments are shown to be similar to the results in this paper, but with a different configuration of the amplifier.
Book ChapterDOI
Radiative Decay, Diffusion, Localization and Dephasing of Trions and Excitons in CdTe Quantum Wells
M. T. Portella-Oberli,V. Ciulin,J. D. Ganiere,Benoit Deveaud,Piotr Kossacki,M. Kutrowski,Tomasz Wojtowicz +6 more
TL;DR: In this article, excitons and trions in CdTe modulation-doped quantum well are investigated, as a function of temperature and in the low density regime, by picosecond photoluminescence as well as three-pulse four-wave mixing experiments.
Journal ArticleDOI
Temperature dependence of the photoluminescence lifetime in disordered quantum wires
TL;DR: In this paper, the role of disorder on the temperature dependence of the photoluminescence lifetime was studied and it was shown that at low temperature, the exciton population is not thermalized in disordered quantum wires and that the lifetime is mainly determined by the localization length of an exciton.
Proceedings ArticleDOI
Narrow-linewidth complex-coupled DFB lasers with gain coupling induced byvertical emission
Nguyen Hong Ky,J. Robadey,J. D. Ganiere,C. Gourgon,Denis Martin,Benoit Deveaud,F. K. Reinhart +6 more
TL;DR: In this paper, a GaAs quantum-well complex-coupled DFB laser with gain coupling induced by vertical emission was demonstrated, achieving a spectral linewidth as narrow as 15 MHz and a side-mode suppression ratio larger than 40 dB.
Journal ArticleDOI
Electron relaxation by LO phonons in quantum wires
TL;DR: In this paper, the average single electron relaxation time from an excited level is shown either to increase or decrease as a function of the initial energy, showing the wire size dependent accelerating and energy lowering effects of an additional phenomenological intrasubband thermalization.
