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…
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…
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…
