Inhibition of the Emission of Electromagnetic Modes of Photonic Crystal Cavities with a Top Mirror

By imaging the angular spectrum of optical modes confined within subwavelength volumes, we investigate the impact of metallic and dielectric surrounding layers on the optical emission properties of planar silicon photonic crystal cavity. By scanning a mirr ...

Relativistic effects in spectroscopy and photophysics of heavy-metal complexes illustrated by spin–orbit calculations of [Re(imidazole)(CO)3(phen)]+

Majed Chergui

Spin–orbit coupling (SOC) is an essential factor in photophysics of heavy transition metal com- plexes. By enabling efficient population of the lowest triplet state and its strong emission, it gives rise to a very interesting photophysical behavior and und ...

Carrier capture into semiconductor quantum dots via quantum wire barriers: Localization and thermionic emission effects

Elyahou Kapon, Pascal Gallo, Qing Zhu, Justyna Szeszko

Carrier transport and capture paths via barriers of different dimensionality in AlGaAs/GaAs quantum wire (QWR)/quantum dot (QD) heterostructures, grown in inverted pyramids, are studied by photoluminescence (PL) spectroscopy. Evidence for thermally activat ...

Investigation of the In composition in InGaN/GaN quantum wells deposited by MOVPE and/or MBE with emission from violet to green

Nicolas Grandjean, Denis Martin, Nils Asmus Kristian Kaufmann

Transmission electron microscopy and photoluminescence investigations have been carried out on a series of quantum wells grown by molecular beam epitaxy and metal organic vapour phase epitaxy. In both cases, the emission wavelength and the peak width agree ...

Scanning Tunneling Microscopy and Luminescence of Individual Nanostructures

Theresa Lutz

A detailed investigation and characterization of the local properties of individual nanoscopic structures is of great importance for the understanding of novel physical phenomena at the nanoscale as well as for the assessment of their possible use in futur ...

Cold Ion Spectroscopy of Biological Molecules in the Gas Phase

Natalia Nagornova

The three-dimensional (3D) structures of proteins and peptides in vivo largely determine their biological functions. In vitro these native structures and their heterogeneity reflect a subtle balance between noncovalent intramolecular interactions and those ...

A novel class of coherent light emitters: polariton lasers

Nicolas Grandjean, Raphaël Butté

The specificities of polariton lasers-a new generation of coherent light-emitting devices where the relaxation of the bosonic quasiparticles responsible for the light emission, the polaritons, is stimulated whereas the photon emission process issued from t ...

Using data collected with the LHCb detector in proton-proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decay B-s(0) -> J/psi f(0)(980) is observed. This CP eigenstate mode could be used to measure mixing-induced CP violation in the B? sy ...

Phonon-Mediated Coupling of InGaAs/GaAs Quantum-Dot Excitons to Photonic Crystal Cavities

Elyahou Kapon, Alok Rudra, Vincenzo Savona, Benjamin Dwir, Pascal Gallo, Kirill Atlasov, Guillaume Jean Tarel, Milan Calic

We demonstrate that the emission characteristics of site-controlled InGaAs/GaAs single quantum dots embedded in photonic crystal slab cavities correspond to single confined excitons coupled to cavity modes, unlike previous reports of similar systems based ...
