12:00 – 1:00 p.m.






We explore the impact of sub-wavelength structural control on optical dispersion, optical forces, and optical nonlinearity in nanophotonic systems.  Through a fundamental examination of energy and force, we show that optical forces in nanostructured systems radically change the nature of nonlinear interactions.  Strong light-boundary interactions yield new forms of Brillouin nonlinearity that produce tailorable coherent phonon emission in nanophotonic systems. Exploiting these strong light-matter interactions, we demonstrate stimulated Brillouin scattering in silicon waveguides for the first time, yielding radically enhanced and tailorable third order nonlinearities.
