Phase-resolved wide-field CARS microscopy with speckle illumination
Federico Vernuccio, Pascal Berto, Baptiste Marthy +5
Coherent anti-Stokes Raman scattering (CARS) microscopy enables label-free chemical imaging of biological samples and materials. Conventionally, CARS is implemented using a point-s…
Single Nanoparticle Dynamics in Opto-Thermal Tweezers: Resolving the Temporal Resolution of Depletion Force Trapping
Jinchao Chen, Robert Talla Kontchou, Saurabh Rai +4
Optothermal tweezers enable the manipulation of a wide range of nano-objects through optically induced depletion forces. Despite significant advances, the temporal dynamics of opto…
Suppressing Plasmonic Heating in Aqueous Environments with Hexagonal Boron Nitride
Martina Russo, Roland van der Vegt, Bohai Liu +5
Optical heating of plasmonic nanostructures is a critical challenge in nanoscale systems. Although plasmonic effects enable enhanced optical functionalities, the associated tempera…
Quantitative phase microscopies: accuracy comparison
Patrick C. Chaumet, Pierre Bon, Guillaume Maire +2
This article presents a thorough comparison of themain QPM techniques, focusing on their accuracy in terms of measurement precision and trueness. We focus on 8 techniques, namely d…
Cross-grating phase microscopy (CGM): In-silico experiment (insilex) algorithm, noise and accuracy
Baptiste Marthy, Guillaume Baffou
Cross-grating phase microscopy (CGM) is a quantitative phase microscopy technique based on the association of a 2-dimensional diffraction grating (cross-grating) and a regular came…
Cross-grating phase microscopy for nanophotonics
Guillaume Baffou
Quantitative phase microscopies (QPMs) have been mainly used for applications in cell biology, for around 2 decades. In this article, we show how cross-grating phase microscopy (CG…
Quantitative phase microscopy using quadriwave lateral shearing interferometry (QLSI): principle, terminology, algorithm and grating shadow description
Guillaume Baffou
Quadriwave lateral shearing interferometry (QLSI) is a quantitative phase imaging technique based on the use of a diffraction grating placed in front of a camera. This grating crea…
Quantifying the Role of the Surfactant and the Thermophoretic Force in Plasmonic Nano-Optical Trapping
Quanbo Jiang, Benoît Rogez, Jean-Benoît Claude +2
Plasmonic nano-tweezers use intense electric field gradients to generate optical forces able to trap nano-objects in liquids. However, part of the incident light is absorbed into t…
Metasurface optical characterization using quadriwave lateral shearing interferometry
Samira Khadir, Daniel Andrén, Ruggero Verre +5
An optical metasurface consists of a dense and usually non-uniform layer of scattering nanostructures behaving as a continuous and extremely thin optical component, with predefined…
Simple experimental procedures to distinguish photothermal from hot-carrier processes in plasmonics
Guillaume Baffou, Ivan Bordacchini, Andrea Baldi +1
Light absorption and scattering of plasmonic metal nanoparticles can lead to non-equilibrium charge carriers, intense electromagnetic near-fields, and heat generation, with promisi…
Temperature Measurement in Plasmonic Nanoapertures used for Optical Trapping
Quanbo Jiang, Benoît Rogez, Jean-Benoît Claude +2
Plasmonic nanoapertures generate strong field gradients enabling efficient optical trapping of nano-objects. However, because the infrared laser used for trapping is also partly ab…
Plasmonic Nanoparticle Networks for Light and Heat Concentration
