Étude des propriétés optiques et dynamiques des boîtes quantiques InAsP/InP(001); Application à la réalisation de sources de photons uniques et lasers à cristaux photoniques émettant à 1.5 µm

Abstract : The last century saw the advent of quantum mechanics, information processing and integrated optics. These fields lead to the integrated optics for quantum communication. One of the challenges is the development of single photon sources and compact lasers operating at telecommunication wavelength, for quantum cryptography and quantum information applications. In this work, we present an optical study of InAsP/InP [001] quantum dots, obtained by MetalOrganic Vapour Phase Epitaxy (MOVPE). It has been demonstrated, through spectral measurements and time-resolved photoluminescence experiments, that these quantum dots present the characteristics necessary for the applications mentioned. Specifically, we have performed measurments with single dots and we clearly observed a photon antibunching. This quantum behaviour, validates the feasibility of a single photons source at telecommunication wavelength. In parallel, studies on photonic crystal lasers, with low modal volume and high quality factor, using the same quantum dots at room temperature, showed original properties, specially near the threshold region of the lasing transition. The difference between conventionnal lasers and our structures is explained with the high spontaneous emission coupling through the cavity mode.
