Epitaxial Nanophotonics · CREOL · University of Central Florida
We engineer the photonic and electronic properties of semiconductors from the atomic layer up — building quantum-limit detectors for quantum information science alongside emerging devices the field does not yet have, from UVC laser diodes to heteroepitaxial mid-infrared emitters.
What we work on
Epitaxial Nanophotonics & Integrated Design
The design philosophy underneath everything else in the lab.
Quantum-limit Devices
Nanophotonic avalanche photodiodes chasing single-photon sensitivity.
UVC Laser Diodes
Pseudomorphic digital alloys for a laser diode that has resisted the field for decades.
High-index Nanophotonics
Exotic modes that only exist once the refractive index is high enough.
Mission
We develop emerging materials and devices across the optoelectronic spectrum, from ultrawide-bandgap (UWBG) nitride heterostructures for UVC applications to high-refractive-index platforms for compact photonic circuits and IV–VI compounds for the mid-infrared. By tailoring material properties and device architectures, we explore new ways to generate, guide, and detect light.
Most importantly, students here learn the full optoelectronic device stack. A project runs from band-structure and electromagnetic design, through epitaxial growth on our own MBE systems, into cleanroom fabrication, and out the other end as a packaged device on a measurement bench. Owning all four stages in one group is unusual, and it is what turns a student into an independent device engineer.
