Title: Integrated Optical Chem-Bio Sensors and Microacoustic Cytometry

A large fraction of existing and proposed sensors rely on microresonators (i.e., acoustical, mechanical, etc). Each resonator modality has its unique properties, and optical microresonators in particular are sensitive to the dielectric constant of adsorbed layers, which in turn depends on electronic and vibronic excitations.
Furthermore, these optical microresonators can cover a large frequency range in the electromagnetic spectrum, from UV to terahertz frequencies. In this talk I will present our work on integrated microring waveguide sensors, (which probe adsorbed molecules in the near-IR) and show our progress in plasmonic and metamaterial sensors working from visible to far-IR wavelengths. Finally I will describe our work on miniature flow cytometry based on microfluidics, microacustics and optical detection.
