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…
