8:35 AM - 9:10 AM: Colorimetric metasurfaces for next-generation on-chip imaging of tissue microstructure

Lisa Poulikakos, Univ. of California, San Diego (United States)

The origin and progression of a variety of leading health challenges, encompassing Alzheimer’s disease, heart disease, fibrosis and cancer, are directly linked to changes in the presence and orientation of fibrous matter in biological tissue. Here, we leverage the unique properties of anisotropic, colorimetric metasurfaces to scale down the complex manipulation of light and selectively visualize disease-relevant fiber density and orientation in biological tissue. Starting with the example of breast cancer diagnostics, we then expand our view to the rich palette of fiber-affecting diseases where metasurfaces hold great potential as rapid, precise, and low-cost tissue diagnostics with facile clinical implementation.

Lisa Poulikakos is an Assistant Professor in Mechanical and Aerospace Engineering at UC San Diego. She received her PhD at ETH Zürich, where she studied chiral nanophotonics in the near and far field. Her postdoctoral research at Stanford University focused on developing functional nanophotonic surfaces for all-optical, on-chip and label-free cancer tissue diagnostics. She is a recipient of the ETH Medal, awarded to outstanding doctoral theses, the L’Oréal USA For Women in Science Fellowship, the SNSF Early Postdoc Mobility Fellowship, the UCSD MRSEC New Investigator Award and was Chair of the 2018 Gordon Research Seminar in Plasmonics and Nanophotonics.

9:10 AM - 9:20 AM: Q&A

9:20 AM - 9:55 AM: Petascale photonic connectivity for energy efficient AI computing

Keren Bergman, Columbia Univ. (United States)

High-performance data centers are increasingly bottlenecked by the energy and communications costs of interconnection networks. Our recent work has shown how integrated silicon photonics with comb-driven dense wavelength-division multiplexing can scale to realize Pb/s chip escape bandwidths with sub-picojoule/bit energy consumption. We use this emerging interconnect technology to introduce the concept of embedded photonics for deeply disaggregated architectures. Beyond alleviating the bandwidth/energy bottlenecks, the new architectural approach enables flexible connectivity tailored for specific applications.

Keren Bergman is the Charles Batchelor Professor of Electrical Engineering at Columbia University where she also serves as the Faculty Director of the Columbia Nano Initiative. Prof. Bergman received the B.S. from Bucknell University in 1988, and the M.S. in 1991 and Ph.D. in 1994 from M.I.T. all in Electrical Engineering. At Columbia, she leads the Lightwave Research Laboratory encompassing multiple cross-disciplinary programs at the intersection of computing and photonics. Prof. Bergman is the recipient of the 2016 IEEE Photonics Engineering Achievement Award and is a Fellow of Optica and IEEE.
