Spectral control of high order harmonics through non-linear propagation effects
M. Hussain, S. Kaassamani, T. Auguste +13
High harmonic generation (HHG) in crystals has revealed a wealth of perspectives such as all-optical mapping of the electronic band structure, ultrafast quantum information and the…
Multirhythmicity in an optoelectronic oscillator with large delay
Lionel Weicker, Thomas Erneux, David P. Rosin +1
An optoelectronic oscillator exhibiting a large delay in its feedback loop is studied both experimentally and theoretically. We show that multiple square-wave oscillations may coex…
Enhancing Four-Wave-Mixing Processes by Nanowire Arrays Coupled to a Gold Film
Ekaterina Poutrina, Cristian Ciraci, Daniel J. Gauthier +1
We consider the process of four-wave mixing in an array of gold nanowires strongly coupled to a gold film. Using full-wave simulations, we perform a quantitative comparison of the…
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…
High-fidelity, broadband stimulated-Brillouin-scattering-based slow light using fast noise modulation
Yunhui Zhu, Myungjun Lee, Mark. A. Neifeld +1
We demonstrate a 5-GHz-broadband tunable slow-light device based on stimulated Brillouin scattering in a standard highly-nonlinear optical fiber pumped by a noise-current-modulated…
Slow light with a swept-frequency source
Rui Zhang, Yunhui Zhu, Jing Wang +1
We introduce a new concept for stimulated-Brillouin-scattering-based slow light in optical fibers that is applicable for broadly-tunable frequency-swept sources. It allows slow lig…
