[Heterostructures semiconductrices pour l'électronique de spin et l'information quantique]
Un choix des expériences optiques est présenté, démontrant l'utilité des semiconducteurs dans deux domaines nouveaux de recherche : l'électronique de spin et l'information quantique. D'abord, nous montrons des exemples de manipulation de spin dans des puits quantiques. La lumière est employée pour produire la polarisation de spin et pour la détecter. Ensuite nous discutons de l'application des méthodes optiques dans les études du ferromagnétisme induit par les porteurs dans des puits quantiques. Finalement, nous présentons des exemples de spectroscopie de boites quantiques individuelles liés aux perspectives d'application des boites quantiques en information quantique, en particulier l'utilisation des mesures de corrélation de photons comme outil d'étude des mécanismes d'excitation des boites quantiques.
A selection of optical experiments is presented, demonstrating the utility of semiconductors in two novel areas of research: spintronics and quantum information. First we show examples of spin manipulation in semiconductor quantum wells. The light is used to generate a spin polarization and to detect it. Next we discuss application of optical methods in studies of carrier-induced ferromagnetism in quantum wells. Finally, we present examples of single quantum dot spectroscopy related to perspectives of application of quantum dots in quantum information, and, in particular, the use of photon correlation measurements as a tool to study the quantum dot excitation mechanisms.
