On the design of highly luminescent lanthanide complexes

Presently, phosphors and luminescent materials for lighting, telecommunications, displays, security inks and marking, as well as for probes in biosciences represent one third of the total value of the lanthanides used worldwide. If optical glasses and lase ...

Study of constrained Brownian motion of nanoparticles near an interface using optical tweezers

Martinus Gijs, Thomas Lehnert, Matteo Cornaglia, Raphaël Etienne Jean Trouillon, Hui Yang

We demonstrate a method to determine the Brownian motion and the diffusion coefficient of a nanoparticle in water in a plane that is parallel to a solid boundary and as function of the distance normal to that boundary by using an optical tweezers instrumen ...

Versatile fabrication of PDMS-carbon electrodes for silicone dielectric elastomer transducers

Herbert Shea, Samuel Rosset

We report a novel method for the fabrication of polydimethylsiloxane (PDMS)-carbon composite electrodes for silicone dielectric elastomer transducers. The methodology combines patterning by laser ablation and oxygen plasma induced bonding, producing stretc ...

Optical Mirror from Laser-Trapped Mesoscopic Particles

Johann Rohner, Jean-Marc Fournier

Trapping of mesoscopic particles by optical forces usually relies on the gradient force, whereby particles are attracted into optical wells formed by landscaping the intensity of an optical field. This is most often achieved by optical Gaussian beams, inte ...

Control of cavity lifetime of 1.5 mu m wafer-fused VCSELs by digital mirror trimming

Elyahou Kapon, Grigore Suruceanu, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Zlatko Mickovic, Dalila Ellafi

Digital chemical etching is used to trim the output mirror thickness of wafer-fused VCSELs emitting at a wavelength near 1.5 mu m. The fine control of the photon cavity lifetime thus achieved is employed to extract important device parameters and optimize ...

Nonlinear relaxation and selective polychromatic lasing of confined polaritons

Benoît Marie Joseph Deveaud, Gabriele Grosso, François Morier-Genoud, Marcia Portella Oberli, Stéphane Trebaol

Polaritons have often been proposed as promising candidates for the realization of all-optical devices due to the easy manipulation and control of their density and spin. In this paper we present a relaxation mechanism for confined polaritons and its appli ...
