This document outlines doctoral research being undertaken by Reid Kerr, under the supervision of Robin Cohen. In this research, we are investigating the problem of detecting and identifying groups of agents that are collaborating, within a larger population. In the scenarios with which we are primarily concerned, agents may cooperate to further their own interests, despite the fact that this ma...

We present our experimental demonstration of controlling the cavity output intensity of one laser beam with the intensity of another laser beam in a composite system consisting of a collection of three-level ?-type rubidium atoms and an optical ring cavity. When the intensity of the controlling beam is modulated with a square waveform, the cavity output power switches on and off (with a distinc...

We experimentally and theoretically study self-phase modulation by Kerr effect in a liquid filled hollow core photonic crystal fiber. We perform a complete characterization of the linear optical properties of the hollow core photonic bandgap fiber filled with deuterated acetone to determine all the characteristics of the propagation mode. The nonlinear coefficient of the fiber is determined by ...

We investigate nonlinear propagation in the presence of the optical Kerr effect by relying on a rigorous generalization of the standard parabolic equation that includes nonparaxial and vectorial terms. We show that, in the (1 + 1)-D case, both soliton and propagation-invariant pattern solutions exist (while the standard hyperbolic-secant function is not a solution).

2014 Three types of short-time measurements using temporally incoherent light instead of short pulses are described. Electronic dephasing in a polydiacetylene film, vibrational dephasing in dimethylsulfoxide liquid, and relaxation of optical Kerr effect in CS2 and nitrobenzene were observed with femtosecond time resolution.

We demonstrate that a weak defocusing Kerr effect in an optical medium with predominantly quadratic [or chi((2))] nonlinear response can eliminate the parametric modulational instability of plane waves, leading to the existence of stable two-wave dark and vortex spatial solitons.
