Ultra-narrow linewidth self-adaptive photonic oscillator : principle and realization
Mehdi Alouini, Gwennael Danion, Marc Vallet
Highly coherent optical sources are a key element in several fields of physics, in particular in time frequency metrology. Over the past decennia, there has been particular efforts…
Imaging through fog using quadrature lock-in discrimination
Shashank Kumar, Bapan Debnath, Meena M. S. +5
We report experiments conducted in the field in the presence of fog, that were aimed at imaging under poor visibility. By means of intensity modulation at the source and two-dimens…
Label-free microscopy of mitotic chromosomes using the polarization Orthogonality Breaking technique
R. Desapogu, G. Le Marchand, R. Smith +7
The vast majority of the microscopy methods currently available to study biological samples require staining prior to imaging. Nevertheless, the ability to reveal specific cell str…
An all-optical technique enables instantaneous single-shot demodulation of images at high frequency
Swapnesh Panigrahi, Julien Fade, Romain Agaisse +2
High-frequency demodulation of wide area optical signals in a snapshot manner is a technological challenge that, if solved, could open tremendous perspectives in 3D imaging, free-s…
Optoelectronic nibbling of laser linewidth using a Brillouin-assisted optical phase-locked loop
Gwennael Danion, Marc Vallet, Ludovic Frein +2
We demonstrate that the implementation of phase-locked loop forbidding multimode operation of a long Brillouin resonator also leads to a dramatic reduction of the optical phase noi…
Intensity noise self-regulated solid-state laser at 1.5m using an ASHG based Buffer Reservoir
Kevin Audo, Mehdi Alouini
An absorption mechanism based on second-harmonic generation (ASHG) is successfully implemented as a buffer reservoir in a solid-state Er,Yb:Glass laser emitting at telecom waveleng…
