Neodymium Photoluminescence in Whispering Gallery Modes of Toroidal Microcavities
Fedja Orucevic, Jean Hare, Valérie Lefèvre-Seguin
We report on light emission from high-Q neodymium-implanted silica microtoroids. Following the description of the fabrication process of microtoroids, neodymium light emission is a…
Transmittance and near-field characterization of sub-wavelength tapered optical fibers
Fedja Orucevic, Valérie Lefèvre-Seguin, Jean Hare
We have produced high transmission sub-wavelength tapered optical fibers for the purpose of whispering gallery mode coupling in fused silica microcavities at 780 nm. A detailed ana…
Room Temperature Lasing of InAs/GaAs Quantum Dots in the Whispering Gallery Modes of a Silica Microsphere
Sébastien Steiner, Jean Hare, Valérie Lefèvre-Seguin +1
We have achieved low threshold lasing of self-assembled InAs/GaAs quantum dots coupled to the evanescent wave of the high- whispering gallery modes of a silica microsphere. In s…
