New method for residual amplitude modulation control in fibered optical experiments

When locking the frequency of a laser to an optical cavity resonance, the residual amplitude modulation (RAM), which accompanies the phase modulation necessary to build the error signal, is a major limitation to the frequency stability. We show that…

Imaging through fog using quadrature lock-in discrimination

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 twodimensional quadrature lock-in detection by software at the receiver, a…

Theory of mode-locked lasers based on non-conventional cavity modes

Cette thèse de doctorat porte principalement sur la dynamique et la robustesse d’un nouveau concept de verrouillage de mode dans les nanolasers semi-conducteurs ultracompacts. Un tel nanolaser présente des modes ermites-gaussiens créés par une…

A microfluidic device to statistically determine the distribution of sickle red cell subpopulations using bioimpedance

Bioimpedance measurements using microfluidic systems play an increasingly important role in cell analysis. In this paper, a microfluidic device mimicking the vasculature, in particular blood microcapillaries, and equipped with electrodes for…
