Bernini, R. (author), De Nuccio, E. (author), Minardo, A. (author), Zeni, L. (author), Sarro, P.M. (author)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...conference paper 2007
