Yellow stimulated emission from Dy-doped silica glass microspheres
Abhishek Sureshkumar, Jonathan Demaimay, Georges Perin +9
Dy-doped silica glass whispering gallery mode microspheres are fabricated by fiber fusion splicing. They present an almost ideal spherical morphology with a radius ranging f…
High-Q Whispering-Gallery-Modes Microresonators in the Near-Ultraviolet Spectral Range
Georges Perin, Yannick Dumeige, Patrice Féron +1
High- whispering gallery mode microresonators are cornerstones to develop compact coherent sources like single frequency lasers or frequency combs. This work reports a detailed…
Narrow Linewidth near-UV InGaN Laser Diode based on External Cavity Fiber Bragg Grating
Antoine Congar, Mathilde Gay, Georges Perin +8
We realize a fiber Bragg grating InGaN based laser diode emitting at 400 nm and demonstrate its high coherency. Thanks to the fabrication of a narrow band fiber Bragg grating in th…
Intracavity Brillouin gain characterization based on cavity ringdown spectroscopy
Ananthu Sebastian, Stéphane Trebaol, Pascal Besnard
We report a technique based upon the cavity ringdown method that enables to characterize the Brillouin gain coefficient directly in a laser cavity. Material gain, optical cavity pa…
Relative Intensity Noise in a Multi-Stokes Brillouin Laser
Ananthu Sebastian, Irina V. Balikereva, Schadrac Fresnel +2
We investigate the Relative Intensity Noise (RIN) properties of a multi-Stokes Brillouin fiber ring laser. We experimentally analyse intensity noise of each Stokes waves and study…
Dephasing effects on coherent exciton-polaritons and the breaking of the strong coupling regime
Naotomo Takemura, Stéphane Trebaol, Anderson Mitchell David +4
Using femtosecond pump-probe spectroscopy, we identify excitation induced dephasing as a major mechanism responsible for the breaking of the strong-coupling between excitons and ph…
Polaritonic Feshbach Resonance
Naotomo Takemura, Stéphane Trebaol, Michiel Wouters +2
A Feshbach resonance occurs when the energy of two interacting free particles comes to resonance with a molecular bound state. When approaching this resonance, dramatic changes in…
Polychromatic polariton laser selector switch
G. Grosso, S. Trebaol, M. Wouters +3
Integration of optical elements into scalable chips has been at the center of a large effort in recent years. Concurrently, the separation between the diverse functions, namely swi…
Stochastic resonance in collective exciton-polariton excitations inside a GaAs microcavity
Hadis Abbaspour, Stéphane Trebaol, Marcia Portella-Oberli +1
We report the first observation of stochastic resonance in confined exciton-polaritons. We evidence this phenomena by tracking the polaritons behavior through two stochastic resona…
Heterodyne Spectroscopy of Polariton Spinor Interactions
Naotomo Takemura, Stéphane Trebaol, Michiel Wouters +2
We report on spinor polariton interactions in GaAs based microcavities. This investigation is carried out by means of heterodyne polarized pump-probe spectroscopy. We show the depe…
