General Introduction

My research group develops infrared semiconductor photonic devices and materials for sensing, imaging, and quantum technologies. We focus on compound semiconductor heterostructures, including superlattices and quantum dots, that enable efficient generation and detection of light across the near-, short-, mid-, and long-wave infrared.

Our work integrates epitaxial materials growth, nanofabrication, and optical spectroscopy to engineer light–matter interactions in semiconductor structures. By controlling carrier dynamics, optical extraction, and photonic environments, we develop new device architectures such as high-power infrared emitters, large-format LED arrays for thermal scene projection, and nanostructured photonic devices for sensing applications.

Current research directions include metamaterial-enhanced infrared emitters, quantum-dot single-photon sources, and integrated photonic platforms for quantum sensing and communication. These technologies support applications ranging from environmental monitoring and chemical sensing to defense imaging systems and emerging quantum photonic networks
