archives@tulane.edu / Quantum nonlinear optics has opened up avenues to defy the measurement, sensing, and amplification limits inherent in classical physics. Separately, the use of multimode or spatially structured states in light-based communications allows for remarkable increases in the amount of information that may be transferred by an individual communication or light pulse. In this dissertation, we apply these two boundary-pushing concepts to several experimental projects, with a primary goal to hasten and facilitate the implementation of quantum and classical free-space optical communications schemes into real-life scenarios. We start by applying neural networks to the optimization of spatially-structured and pulsed light communications in Chapter 2, wherein our networks successfully learn to predict distorted optical pulses and classify noisy light patterns carrying non-zero orbital angular momentum. Chapter 3 focuses on four-wave mixing, a nonlinear light-matter interaction in atomic vapor that we use to construct quantum-correlated light beams with nontrivial structures as well as a novel phase-sensitive amplifier. Finally, we continue to take advantage of the complex nonlinear response of atomic vapor in Chapter 4, this time to create "self-regenerating" light beams whose cross-sections resemble Bessel-Gauss functions. / 1 / Erin Knutson
