Paper Abstract

Design, fabrication and test of an optofluidic device are presented. It is constituted of a circular waveguide crossing a fluidic channel integrated in a monolithic LiNbO3 wafer. The fluidic channel is realized by precision sawing and the optical waveguide is induced by photorefractive beam self-trapping controlled by the pyroelectric effect. The self-aligning property of this latter writing technique allows both, efficient light coupling inside the channel and light collection after channel crossing. It is shown that the refractive index of a liquid present in the fluidic channel can be accurately evaluated by simple monitoring of the light transmitted through the waveguide.
