Specialty Optical Fibers/Negative Curvature Fibers
The emerging technology of chalcogenide glass fiber devices promises to transform mid-IR sensor technologies. The research on specialty optical fibers for mid-IR applications includes mid-IR supercontinuum generation, chalcogenide glass mid-IR fiber lasers, and hollow-core chalcogenide negative curvature fibers.

Hollow-core negative curvature fibers using the antiresonance guiding mechanism have a low transmission loss and a wide transmission bandwidth. The simple negative curvature structure could be used to fabricate fiber devices using non-silica glasses, such as chalcogenide, for mid-IR applications.

2-D materials
2D Materials, or single layer materials, are materials consisting of a single layer of atoms. Due to their unusual characteristics, 2D materials have applications such as photovoltaics, semiconductors, electrodes and water purification.

Nanophotonics and metamaterials
Nanophotonics is the study of the behavior of light on the nanometer scale. Our interest is to design different structures for photovoltaic and biomedical application. We will also investigate different metamaterials with negative refractive index.

Nanophotonic circuits based on surface plasmons have experienced rapid development with tighter confinement and more complex functionalities. The integration of plasmonic elements with electrical counterparts remains challenging. The two-dimensional (2D) materials display great potential for a range of applications, including electronic-photonic integrated circuits.
