Cadmium selenide nanoplatelets (a two-dimensional variant of the quantum dot) are increasingly used in optical devices due to their bright and tunable emission characteristics.

However, to use these colloidal particles in practical photonic devices, the direct patterning of micron-scale features remains a grand-challenge.

Using thin-film fabrication and UV lithography tools inside the URnano cleanroom, we have been able to direct-write nanoplatelet patterns inside Fabry-Perot cavities with features as small as one micron, and show strong light-matter coupling with greater Rabi splitting than typically seen in this geometry due to stronger lateral electric field confinement.

The capability to create arbitrary patterns in nanoplatelet films will enable the fabrication of chiral meta-structures which opens up the possibility to observe and study chiral strong light-matter coupling and exciton-polariton photo-physics.

We created model retinas for fundus imaging, which simulate several parts of the retina.

This work investigates material birefringence as a means to determine microplastic identity in samples.

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.

The 3D printing project aims to design, create, and test a polymer printed part that houses a f/5.6, eight element system. After the system was completed, repeatability measurements were done along with testing our procedure on the similar f/8 system.
