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.
