"Nonlinearity Management in Optics: Experiment, Theory, and Simulation"

My paper, Nonlinearity Management in Optics: Experiment, Theory, and Simulation, just got published in Physical Review Letters.

As I mentioned in an earlier entry, this is my first ever PRL. It has been highlighted in Physical Review Focus. A blurb is slated to be published in Laser Focus World and Caltech is considering making a press release about this work.

This was also my first work in which I did stuff really closely with experimentalists. The authors and the abstract are below.

Authors: Centurion, Martin; Porter, Mason A.; Kevrekidis, P. G.; and Psaltis, Demetri

Abstract: We conduct an experimental investigation of nonlinearity management in optics using femtosecond pulses and layered Kerr media consisting of glass and air. By examining the propagation properties over several diffraction lengths, we show that wave collapse can be prevented. We corroborate these experimental results with numerical simulations of the (2+1)-dimensional focusing cubic nonlinear Schrödinger equation with piecewise constant coefficients and a theoretical analysis of this setting using a moment method.

This would be called a multi-layer "Kerr sandwich."
