Our current work focuses on advancing photonic and optoelectronic technologies in the mid-infrared (MIR) and terahertz (THz) spectral regions. We are developing various types of devices/systems in these spectral regions, including:


light sources (both coherent and incoherent light sources);

photodetectors and focal plane arrays;

waveguides, modulators and switches;

chemical and biological sensors;



Our goal is to keep expanding the technology frontiers towards more advanced functionalities, higher performance, lower cost and smaller footprint.


To achieve these goals, we are exploring new materials (2D materials, strongly correlated electron materials) and engineered structures (semiconductor heterostructures, metamaterials), novel device operation principles and architectures, as well as advanced device fabrication processes.


At the same time, we are also actively investigating  the fascinating physics underlying the intriguing properties/characteristics of different materials, engineered micro- and nano-structures and the variety of photonic and optoelectronic devices.
