We study the integration of plasmonic traps with microfluidic channels. Plasmonic traps are optical traps that use the evanescent field generated by metallic nanostructures at their plasmon resonance to trap small objects. Contrary to conventional - far-fi ...

The dispersive properties of waves are strongly affected by inevitable residual disorder in man-made propagating media, in particular in the slow wave regime. By a direct measurement of the dispersion curve in k space, we show that the nature of the guided ...
In this paper, we study the multiple scattering by electrically small (the radius of the cylinder is much smaller than the wavelength) plasmonic nanocylinders near surface plasmon resonance. The cylinders are assumed to be identical in dimension and compos ...
The propagation of surface plasmon polaritons guided along Au metal waveguides fabricated by electron-beam lithography is experimentally investigated using simultaneous near-field excitation and detection of plasmon-polariton modes localized at the air/Au ...
Cavity-enhanced radiation-pressure coupling of optical and mechanical degrees of freedom gives rise to a range of optomechanical phenomena, in particular providing a route to the quantum regime of mesoscopic mechanical oscillators. A prime challenge in cav ...
n this paper we investigate for the first time the near-field optical behavior of two-dimensional Fibonacci plasmonic lattices fabricated by electron-beam lithography on transparent quartz substrates. In particular, by performing near-field optical microsc ...
A nanomosaic network of metallic nanoparticles for the detection of ultralow concentrations of proteins is reported, which uses two planar microelectrodes embedded in a microchip that permit generation of capacitive coupling to the nanomosaic system withou ...
The spatial distribution of surface electromagnetic waves on a one-dimensional photonic crystal with a polymeric grating on top is mapped using a multiheterodyne scanning near-field optical microscope. The grating opens a bandgap. At the band edges, a stat ...
Surface plasmon-polaritons (SPPs) – electromagnetic waves propagating on the boundary between a metal and a dielectric and tightly bound to the interface – have been known for years. Recent progresses in microfabrication methods, near-field characterizatio ...
The molecular orientation of Cy5-labeled target DNA hybridized on a probe DNA layer was studied on a planar waveguide in the Kretchmarm configuration at various target DNA bulk concentration. Optical waveguide fluorescence spectroscopy (OWFS) was employed ...
