Exploring van der Waals materials with high anisotropy: geometrical and optical approaches
We developed a geometric approach to identify highly anisotropic materials. This leads to the discovery of giant anisotropy of As2S3, enabling the record-small quarter-wave plate.

Transient stimulated Raman scattering spectroscopy and imaging
A time-domain excitation strategy for stimulated Raman scattering was achieved by manipulating vibrational wave packet interference. The new method enables simultaneous sub-mM level sensitivity and natural-linewidth-limit Raman spectra.

High-performance terahertz modulators induced by substrate field in Te-based all-2D heterojunctions
We have introduced Te-based all-2D heterojunctions as optically controlled terahertz modulators to significantly promote the device performances and elaborated their charge dynamics driven by substrate effect through first-principles calculations.

Chiral transmission by an open evolution trajectory in a non-Hermitian system
We explore an open trajectory linking two infinite points having the same asymptotic eigenmodes, demonstrating that this platform enables high-efficiency chiral transmission, with each eigenmode localized in a single waveguide.
