High-order optical nonlinearity at low light levels
Joel A. Greenberg, Daniel J. Gauthier
We observe a nonlinear optical process in a gas of cold atoms that simultaneously displays the largest reported fifth-order nonlinear susceptibility χ^(5) = 1.9x10^{-12} (m/V)^4 an…

All-Optical Switching with Transverse Optical Patterns
Andrew M. C. Dawes, Lucas Illing, Joel A. Greenberg +1
We demonstrate an all-optical switch that operates at ultra-low-light levels and exhibits several features necessary for use in optical switching networks. An input switching beam,…
