Title:
======
Exploring nanophotonics to tailor the laws of physics
-----------------------------------------------------------
Abstract:
=========
By nano-structuring materials at length scales smaller than the wavelength
of light, one can create effective materials, exhibiting optical
properties unparalleled in any naturally occurring materials. The power of
this approach is illustrated with two particularly important examples.
Firstly, it is shown that the control over the density of photonic states
via such effective materials provides a control over black body emission,
which can now be tailored almost at-will. It is also shown that such
materials offer unprecedented opportunities for tailoring the near-field.
In the photonic near-field, thermal transfer can be orders of magnitude
stronger at a given temperature than the black-body thermal transfer. And
since over 90% of all primary energy sources are converted into electrical
and mechanical energy via thermal processes, exciting energy-related
applications could be enabled. Secondly, by exploring time-reversal
symmetry breaking in non-trivial topological states, it is shown that one
can create a very unusual optical phenomenon: photonic edge states that
propagate in only one direction. This phenomenon is closely related to
quantum-Hall edge states, and is in marked contrast to the conventional
behavior of light, whose propagation is always bi-directional. This effect
is directly implemented to create one-way waveguides, in which
backscattering (and hence Anderson localization) cannot exist. In such
peculiar waveguides, light is immune to disorder and can even travel right
around large obstacles without any loss in energy.

Short Bio:
========
Marin Soljačić received a BsE degree in physics and a BsE degree in
electrical engineering from MIT in 1996. He earned his PhD in physics at
Princeton University in 2000. In September 2000, he was named an MIT
Pappalardo Fellow in Physics, and in 2003 was appointed as a Principal
Research Scientist in the Research Laboratory of Electronics at MIT. In
September 2005, he became an Assistant Professor of Physics at MIT, in
July 2010 an Associate Professor of Physics at MIT, and in July 2011 a
Full Professor of Physics. His main research interests are in
electromagnetic phenomena, focusing on nanophotonics, non-linear optics,
and wireless power transfer. He is a co-author of 126 scientific articles
and 31 issued US patents, and he has been invited to give more than 100
invited talks at conferences and universities around the world. He is the
recipient of the Adolph Lomb medal from the Optical Society of America
(2005), and the TR35 award of the Technology Review magazine (2006). In
2008, he was awarded a MacArthur fellowship grant. He is a correspondent
member of the Croatian Academy of Engineering since 2009. In 2011 he
became a Young Global Leader (YGL) of the World Economic Forum.
