Integrated Photonics for Sensing Applications

Anu Agarwal is a Principal Research Scientist at MIT, where she is developing an integrated Si-CMOS compatible platform of linear and non-linear materials for photonic devices and systems, especially in the mid-IR regime, for hyperspectral imaging and chem-bio sensing, because most chemical pollutants and biological toxins have their fingerprints in this range. Benjamin Miller joined the University of Rochester faculty in 1996, where he is currently Dean’s Professor of Dermatology, Biochemistry and Biophysics, Biomedical Engineering, and Optics. His group’s expertise in interferometric and photonic sensing has been applied to the development of several novel optical biosensor platforms, and his group’s work on RNA-targeted drug discovery has resulted in synthetic compounds targeting RNAs involved in several human diseases. Juejun (JJ) Hu is currently the John F. Elliott Professor of Materials Science and Engineering at MIT. His primary research interest covers new optical materials exemplified by chalcogenide compounds, as well as enhanced photon-matter interactions in nanophotonic structures. He has authored and coauthored over 150 refereed journal publications and technologies developed in his lab have led to several spin-off companies.
