Dye-Doped ZnO Microcapsules for High Throughput and Sensitive Optofluidic Micro-Thermometry

The main objective of this work is to show the proof of concept of a new optofluidic method for high throughput fluorescence-based thermometry, which enables the measure of temperature inside optofluidic microsystems at the millisecond (ms) time…

Electrical Sensing of sickled red blood cells subpopulations in microfluidic device

This paper discusses the electrical sensing of red blood cell (RBC) rigidity due to Hemoglobin S (HbS) polymerization in sickle cell disease. For this purpose sickle RBCs subpopulations, differentiated by cell density, were flown through a…

Traitement du signal et de l'image

Investigation of analog signal distortion introduced by a fiber phase sensitive amplifier

We numerically simulate the distortion of an analog signal carried in a microwave photonics link containing a phase sensitive amplifier (PSA), focusing mainly on amplitude modulation format. The numerical model is validated by comparison with…

Optimization of laser dynamics for active stabilization of DF-VECSELs dedicated to cesium CPT clocks

We report the implementation and performance of a double servo-loop for intensity and phase-difference active stabilization of a dual-frequency vertical external-cavity surface-emitting laser (DF-VECSEL) for coherent pop- ulation trapping (CPT) of…

Oxidative stress activates red cell adhesion to laminin in sickle cell disease

Vaso-occlusive crises are the hallmark of sickle cell disease (SCD). They are believed to occur in two steps, starting with adhesion of deformable low-dense red blood cells (RBCs), or other blood cells such as neutrophils, to the wall of post…

Dynamics of mode-locked nanolasers based on Hermite-Gaussian modes

The different dynamical behaviors of the Hermite-Gaussian (HG) modes of mode-locked nanolasers based on a harmonic photonic cavity are investigated in detail using a model based on a modified Gross-Pitaevskii Equation. Such nanolasers are shown to…
