Brightness and purity of a room-temperature single-photon source in the blue-green range
Francis Granger, Saransh Raj Gosain, Gilles Nogues +4
Single-photon sources are crucial for developing secure telecommunications. However, most systems operate at cryogenic temperatures. Here, we discuss a promising solid-state system…
AlGaN/GaN asymmetric graded-index separate confinement heterostructures designed for electron-beam pumped UV lasers
Sergi Cuesta, Yoann Curé, Fabrice Donatini +9
We present a study of undoped AlGaN/GaN separate confinement heterostructures designed to operate as electron beam pumped ultraviolet lasers. We discuss the effect of spontaneous a…
Hybrid KTP-plasmonic nanostructures for enhanced nonlinear optics at the nanoscale
Nicolas Chauvet, Maeliss Ethis de Corny, Mathieu Jeannin +6
The search for miniaturized components for nonlinear optical processes needs a way to overcome the efficiency loss due to the effective size reduction of the active medium. We inve…
Photon-pair production at the nanoscale with hybrid nonlinear/plasmonic antennas
Guillaume Laurent, Nicolas Chauvet, Gilles Nogues +2
Integration of photon pairs nanosources is a major challenge for quantum technology. In this context, we develop a formalism for the investigation of Spontaneous Parametric Down Co…
Enhanced Photon Extraction from a Nanowire Quantum Dot Using a Bottom-Up Photonic Shell
Mathieu Jeannin, Thibault Crémel, Teppo Häyrynen +4
Semiconductor nanowires offer the possibility to grow high-quality quantum-dot heterostructures, and, in particular, CdSe quantum dots inserted in ZnSe nanowires have demonstrated…
Cathodoluminescence spectroscopy of plasmonic patch antennas: towards lower order and higher energies
Mathieu Jeannin, Névine Rochat, Kuntheak Kheng +1
We report on the cathodoluminescence characterization of Au, Al and a Au/Al bimetal circular plasmonic patch antennas, with disk diameter ranging from 150 to 900 nm. It allows us a…
