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…
