Silicon-PDMS optofluidic integration

In this work we show that integrated Hybrid Silicon-PDMS Antiresonant Reflecting Optical Waveguide (H-ARROW) can be applied for the realization of optofluidic devices. H-ARROW is constituted by the optofluidic channel of a conventional ARROW, sealed with a thin PDMS layer. This layout simplifies the integration of microfluidic parts to manipulate liquid samples, which can be easily fabricated in the PDMS layer. Hybrid ARROWs have been fabricated and used in order to design complex devices like an integrated hybrid liquid core optofluidic ring resonator (h-LCORR) and a hybrid optofluidic platform for fluorescence measurements.
