Shaping light and matter
—nonlinearity, quantum effects, reconfigurability—
and beyond.

MEMS-based Photonic/Optoelectronic Devices
We integrates micro/nanoelectromechanical systems with photonic structures for dynamic, in situ control of light. Mechanical tuning of metamaterials, quantum materials, and photonic crystals enables adaptive light sources, tunable light–matter interactions, and programmable optical functions for next-generation photonic and quantum technologies.

In-situ Tuning and Probing Techniques for 2D Materials
MEMS-based in-situ tuning and probing enables active control and characterization of mechanical, electrical, and optical properties in quantum materials, thin films, and metamaterials, providing a precise platform for reconfigurable nanophotonic and electronic studies.

Reconfigurable Photonic Metamaterials
Reconfigurable photonic metamaterials enable dynamic optical nanocavities with tunable light–matter interactions, controllable nonlinearity, quantum interconnects, and tailored lattice–defect coupling. These advances open new possibilities for nonlinear optics, quantum information, and adaptive photonic technologies.

Advanced Nanofabrication
Advanced nanofabrication enables the creation of precise, complex nanostructures for photonic, electronic, and quantum devices. By integrating novel materials and architectures, this research supports reconfigurable metamaterials, MEMS platforms, and quantum photonic systems, advancing applications in nonlinear optics, quantum information, and adaptive photonics.

Spectroscopy
Our effort includes the development of multifunctional band structure, nonlinear, PL, and Raman spectroscopy, to offer integrated functionalities. We are also expanding the frequency range of spectroscopy studies and driving measurement techniques from the semiclassical to the quantum regime.
