We review our recent progress in bringing fluorescent correlation spectroscopy (FCS) of single molecules on a silicon optofluidic platform. Starting from basic concepts and applications of FCS we move to a description of our integrated optofluidic de

On an integrated optofluidic waveguide platform we implement two complementary types of traps, in a transverse and a novel axial geometry. The traps are characterized and used to manipulate and study biomaterial.

We experimentally demonstrate wavelength filtering of integrated solid- and liquid-core antiresonant reflecting optical waveguide devices with a range of 8-54 dB rejection and 2-29 nm stopbands.

We present a fully planar integrated optofluidic platform that permits single particle detection, manipulation and analysis on a chip. Liquid-core optical waveguides guide both light and fluids in the same volume. They are integrated with fluidic res

We have previously produced antiresonant reflecting optical waveguides (ARROWs) with hollow cores that can guide light through liquid or gas media. In order to utilize these structures in sophisticated sensing applications, we have improved our initi
