Distinguished Seminar Series: "Nonlinear optics at the nanoscale" by Eric Mazur

Tuesday, March 18, 2014 11:00 AM to 12:00 PM
CREOL Room 102

Eric Mazur
Harvard University
Area Dean of Applied Physics

Abstract:
We explore nonlinear optical phenomena at the nanoscale by launching femtosecond laser pulses into long silica nanowires. Using evanescent coupling between wires we demonstrate a number of nanophotonic devices. At high intensity the nanowires produce a strong supercontinuum over short interaction lengths (less than 20 mm) and at a very low energy threshold (about 1 nJ), making them ideal sources of coherent white-light for nanophotonic applications. The spectral broadening reveals an optimal fiber diameter to enhance nonlinear effects with minimal dispersion. We also present a device that permits a number of all-optical logic operations with femtosecond laser pulses in the nanojoule range.

Biography:
Eric Mazur is the Balkanski Professor of Physics and Applied Physics at Harvard University and Dean of Applied Physics. He is a prominent physicist known for his contributions in nano photonics, an internationally recognized educational innovator, a sought-after lecturer, and successful entrepreneur. In education he is widely known for his work on Peer Instruction, an interactive teaching method aimed at engaging students in the classroom and beyond. Mazur has received many awards for his work in physics and in education and has founded several successful companies. Mazur is Chief Academic Advisor for Turning Technologies, a company developing interactive response systems for the education market. Dr. Mazur is author or co-author of 258 scientific publications and 23 patents. He has also written extensively on education and is the author of Peer Instruction: A User's Manual (Prentice Hall, 1997), a book that explains how to teach large lecture classes interactively. In 2006 he helped produce the award-winning DVD Interactive Teaching.
