Raman-free fibered photon-pair source.

Scientific reports

Cordier M, Delaye P, Gérôme F, Benabid F, Zaquine I.
PMID: 32015403
Sci Rep. 2020 Feb 03;10(1):1650. doi: 10.1038/s41598-020-58229-7.

Raman-scattering noise in silica has been the key obstacle toward the realisation of high quality fiber-based photon-pair sources. Here, we experimentally demonstrate how to get past this limitation by dispersion tailoring a xenon-filled hollow-core photonic crystal fiber. The source...

Opt Express. 2019 Aug 19;27(17):24403-24415. doi: 10.1364/OE.27.024403.

We describe a technique that allows the improvement of the resolution of optical microscopes for nanofiber measurements beyond the diffraction limit. It can be readily implemented on any microscope. We demonstrated it by measuring tapered fibers radii from 0.4...

Active engineering of four-wave mixing spectral correlations in multiband hollow-core fibers.

Opt Express. 2019 Apr 01;27(7):9803-9814. doi: 10.1364/OE.27.009803.

We demonstrate theoretically and experimentally a high level of control of the four-wave mixing process in an inert gas-filled inhibited-coupling guiding hollow-core photonic crystal fiber. The specific multiple-branch dispersion profile in such fibers allows both correlated and separable bi-photon...

Using targeted therapies at the end of life.

PMID: 32855229
BMJ Support Palliat Care. 2020 Aug 27; doi: 10.1136/bmjspcare-2020-002529. Epub 2020 Aug 27.

The prescription of chemotherapy during the last weeks of a patient's life is a recognised criterion of decreasing quality of life but also survival. Targeted therapies have a particular efficiency and tolerance profile raising the question of their use...

Enhanced nonlinear interaction in a microcavity under coherent excitation.

Optics express

Serna S, Oden J, Hanna M, Caer C, Le Roux X, Sauvan C, Delaye P, Cassan E, Dubreuil N.
PMID: 26698478
Opt Express. 2015 Nov 16;23(23):29964-77. doi: 10.1364/OE.23.029964.

The large field enhancement that can be achieved in high quality factor and small mode volume photonic crystal microcavities leads to strengthened nonlinear interactions. However, the frequency shift dynamics of the cavity resonance under a pulsed excitation, which is...

Afr J Lab Med. 2014 Jul 23;3(1):126. doi: 10.4102/ajlm.v3i1.126. eCollection 2014.

BACKGROUND: Strengthening the communication and professional relationships between clinicians and laboratory workers is essential in order to positively change clinicians' attitudes about the reliability of diagnostic tests, enhancing the use of laboratory diagnostics and, ultimately, improving patient care. We...

Front Microbiol. 2017 Jan 30;8:29. doi: 10.3389/fmicb.2017.00029. eCollection 2017.

Understanding the relationship between phylogeny and predicted traits is important to uncover the dimension of the predictive power of a microbial composition approach. Numerous works have addressed the taxonomic composition of bacteria in communities, but little is known about...

Self-adapting denoising, alignment and reconstruction in electron tomography in materials science.

An automatic procedure for electron tomography is presented. This procedure is adapted for specimens that can be fashioned into a needle-shaped sample and has been evaluated on inorganic samples. It consists of self-adapting denoising, automatic and accurate alignment including...

Enhancement of nonlinear effects at the degenerate band edge of two-dimensional photonic crystals.

The ability of two-dimensional (2D) photonic crystals (PC) for high enhancements of nonlinear processes is analyzed in the case of a degenerate band edge when two symmetrical diffracted beams are generated by Bragg diffraction in the 2D-PC. Calculations are...

Dislocation density-dependent photorefractive effect in (001)-cut GaAs.

Optics letters

PMID: 19855704
Opt Lett. 1994 Dec 01;19(23):1946-8. doi: 10.1364/ol.19.001946.

We present studies of the photorefractive effect in nonphotorefractive orientations of liquid-encapsulated Czochralski-grown GaAs crystals. Picosecond diffraction experiments conducted in different samples show that a forbidden photorefractive signal correlates well with dislocation density, which points out that the effect...

Macroscopic assays that are traditionally used to investigate the adhesion behaviour of microbial cells provide averaged information obtained on large populations of cells and do not measure the fundamental forces driving single-cell adhesion. Here, we use single-cell force spectroscopy...
