Reststrahlen Optics
The far-IR is arguably one of the few remaining frontiers of the electromagnetic spectrum. It is an extremely challenging wavelength range to work in, with little to no optical infrastructure for either conducting fundamental research or developing optical devices and systems. Our group aims to develop the far-IR, both through the i) demonstration of new approaches to light manipulation and generation to form the foundation of a far-IR optical infrastructure, and in the ii) effort to create a far-IR research infrastructure to better disseminate, encourage, and apply far-IR research. This work is in collaboration with Prof. Daniel Wasserman (UT Austin) and Prof. Ryan Roeder (UND).

Metamaterials
Our research interests are devoted to the modeling, fabrication, characterization and integration of optical metamaterials in the visible and mid-infrared. Our current projects focus on (1) enhancing light-matter interactions in the mid-infrared using sub-diffraction hyperbolic metamaterial resonators, (2) designing and characterizing optical metamaterials based on Mie scattering from 3D lattices of nanoparticles, and (3) implementing super-resolution imaging using 2D metasurfaces. Our work spans modeling, fabrication, and characterization. This work is in collaboration with Prof. Paul Bohn (UND), Prof. David Go (UND), and Prof. Greg Timp (UND).

Deep-ultraviolet Sources
We are working to develop optical materials and devices for the deep-ultraviolet. The ultimate aim of our research is electrically-injected DUV lasers that emit below 270 nm. Our current efforts focus on measuring the gain and internal quantum efficiency of DUV GaN/AlN and GaN/AlGaN quantum well structures grown via molecular beam epitaxy. Our work here is a collaboration with Prof. Farhan Rana, Prof. Grace Xing, and Prof. Debdeep Jena at Cornell University. The ultimate aim of our research is electrically-injected DUV that emit below 270 nm. Our current efforts focus on optically characterizing DUV quantum well structures grown via molecular beam epitaxy.
