Dr. Park's research is centered at discovering new optical phenomena and applications using nanoscale materials and structures and has currently two major thrusts: nonlinear optical devices and biosensing/therapeutics. For nonlinear optical devices. Dr. Park is also developing devices based on chalcogenide glass for operations in the mid-infrared region for sensing, communications, and switching. For biosensing and therapeutics, Dr. Park is developing nanomaterials that efficiently upconvert frequencies and thereby enable new imaging, sensing and/or therapeutic approaches.

ECEN 5915 - Foundations of Quantum Engineering
Primary Instructor
-
Fall 2021
Introduces engineers to quantum theory. In this course you will learn how to describe many different physical systems (such as atoms, electrons, light, mechanical oscillators, and tops) mathematically. It also explores different notions of quantumness such as entanglement and non-contextuality. The foundations obtained in this course are important for further study of quantum hardware (sensors), communication, and computing. Same as ECEN 4915.
