Integrated photonic devices have traditionally been designed for data communications using exclusively solid-state materials. However, a vast area of potential applications, in particular in the life sciences, involve interactions of light with liquids and gases. Recently, a number of optofluidic approaches have been considered that are aimed at integrating such non-solid media with chip-scale photonic structures. We have developed a versatile, planar photonic platform based on hollow-core optical waveguides (ARROWs). I will describe the physical foundations and optical characteristics of ARROWs and a broad range of devices and capabilities that are made possible by this approach, in particular optical analysis of single biomolecules. One example is the fluorescence analysis of single nucleic acids for amplification-free detection of Ebola infection as a new paradigm for molecular diagnostics. I will also describe the implementation of optofluidic wavelength division multiplexing in multi-mode waveguides for identification of single influenza viruses. The expansion of optofluidic capabilities through hybrid integration via nanopore-based electrical detection and integrated sample processing will be discussed. Finally, I will introduce a new, highly reconfigurable photonic platform based on lightvalves that enable independent, dynamic control of fluid and light flow on a chip.BiographyHolger Schmidt received the Ph.D. degree in electrical and computer engineering from the University of California Santa Barbara.
