Engineering the Atom-Atom Interactions within Metamaterials
Xukun Lin, Michele Cotrufo Abstract This thesis uses an effective zero-index photonic crystal to support superradiance of atoms within it. I show that the emitted power of the atoms depends…

Tunable trajectory ultrabroadband flying focus experimental setup using adaptive optics
The goal of this thesis is to design and build a tunable flying focus experimental setup using adaptive optics. The flying focus technique produces an extended intensity peak which moves at a designed focal velocity independent of the medium group velocity. This requires an optical system that can extend the focal region beyond the Rayleigh length as well as impart sufficient radial group delay to achieve spatiotemporal control. An axiparabola is used to extend the focal region and a deformable mirror imparts a user defined radial group delay to achieve spatiotemporal control. The tunability of this technique will be used to optimize secondary source generation experiments such as laser wakefield acceleration and terahertz generation.
