We report on versatile orbital angular momentum beam generation through the association of a 61-channels coherent beam combining digital laser and a liquid-crystal q-plate. Particularly, high-order vortex beams that carry orbital angular momentum are

There are only a few examples in which beads are employed for heterogeneous assays on microfluidic devices, because of the difficulties associated with packing and handling these in etched microstructures. This contribution describes a microfluidic d

In this paper it will be presented different ray trace models that are able to simulate uniaxial birefringent optical elements with twisted structure. There exist already methods to calculate the optical behavior of birefringent elements (including a

We present a recently developed miniature scanning Fourier-Transform spectrometer (ARCspectro ANIR), which is based on a lamellar grating interferometer and uses a micro-mechanical actuator. The small dimensions of the interferometer (35 mm x 35 mm x

This work confirms experimentally the linear dependence of electro-osmotic velocity on an imposed hydrostatic counter pressure. The effect of hydrostatic pressure-induced flow (PH) becomes significant on electroosmotic flow (EOF) in microchannels wit

Possible problems stemming from hydrostatic pressure effects in electrokinetically driven, chip-based analysis systems have been alluded to in the literature, but to date, no detailed study has appeared. This paper discusses the dependence of electro

We have studied the transverse and axial equilibrium positions of dielectric micro-spheres trapped in a single-beam gradient optical trap and exposed to an increasing fluid flow transverse to the trapping beam axis. It is demonstrated that the axial

We present the optical design and realization of a low-resolution liquid-crystal (LC) Fourier-transform spectrometer (FTS). This FTS is based on a polarization interferometer that has a Wollaston prism made of a LC material as a key component. It has

Very high frequency oscillations of intense light fields interact with micron-size dielectric objects to exert dc optical forces that allow polarizable particles to levitate, to be trapped and to be bound. Such optical forces are also suitable to arr
