A hybrid silicon-PDMS optofluidic platform for sensing applications

A hybrid silicon-poly(dimethysiloxane) (PDMS) optofluidic platform for lab-on-a-chip applications is proposed. A liquid-core waveguide with a self-aligned solid-core waveguide and a microfluidic device are integrated with a multilayer approach, resulting in a three-dimensional device assembly. The optofluidic layer was fabricated with a hybrid...

Optofluidics: A new tool for sensing

Over the last years optofluidics has emerged as a very promising field. The integration at microscopic level between optics and microfluidics provides a number of unique characteristics that cannot be obtained with solid materials only. This paper briefly reviews the state of the art on optofluidics for sensing applications. We first describe...

Optofluidics: Waveguides and devices

In this work we review recent results of our work on optofluidics. We show that single mode optofluidic waveguides with low loss can be realized using antiresonant reflecting optical confinement (ARROW). These waveguides can be fabricated using full standard silicon technology or hybrid silicon-polymer processes. ARROW waveguides have been used...

Liquid core integrated ring resonator

We report the design and the fabrication of an integrated optofluidic ring resonator based on liquid core antiresonant reflecting optical waveguide (ARROW) operating around ?=635nm with a water filled core (nc=1.33). This waveguide permits a strong coupling between light and analyte as the same microchannel can be used for delivering sample and...

Integrated silicon optofluidic ring resonator

The feasibility of an integrated silicon optofluidic ring resonator is demonstrated. Liquid core antiresonant reflecting optical waveguides are used to realize a rectangular ring resonator with a multimode interference liquid core coupler between the ring and the bus waveguide. In this configuration the same waveguide used to confine the light...

Integrated silicon optical sensors based on hollow core waveguide

In this work we show that integrated silicon hollow core AntiResonant Reflecting Optical Waveguide (ARROW) can be used as a basic tool for the realization of optical sensors. ARROW waveguides, with hollow core, permit to confine the light in a low refractive index liquid core, by means of two cladding layers designed to form a high reflectivity...
