Testa, G. (author), Huang, Y. (author), Sarro, P.M. (author), Zeni, L. (author), Bernini, R. (author)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...journal article 2010
