Photonic Crystals:

Photonic Crystals are artificially constructed periodic optical microcavities with rich physical properties and broad application prospects, serving as an important platform for studying topological photonics, non-Hermitian optics, and nanophotonics.

The research group achieved highly robust second-harmonic generation in photonic crystals through Brillouin zone folding (Physical Review B, 2025, 111, 15, 155302); and realized directionally tunable nanolasers in BICs through phase-change material-induced loss (Laser & Photonics Reviews, 2025, e00413).

Light field manipulation:

Achieving  precise control over different degrees of freedom of light waves at the nanoscale is a major challenge in the field. Combining topological photonics, phase-change materials, and dynamic tunable technology for nanoscale light field manipulation is an important research direction.

The research group has combined phase-change materials with topological photonics to propose a beam control method based on topological charge splitting and merging (Laser & Photonics Reviews, 2024, 18, 9, 2301233); developed a refractive index-controlled dynamic beam displacement metasurface (Chinese Optics Letters, 2025); and achieved dynamic switching of the orbital angular momentum order of vortex light (Optics Communications, 2025, 583, 131799).

Micro-Nano Optoelectronic devices:

In the process of device miniaturisation, the impact of optical feedback mechanisms, micro-nano fabrication processes, and material structural properties on key parameters such as performance, power consumption, and speed of micro-nano optoelectronic devices is a research focus.

The research group resolved the compatibility issues between metal sodium thin films and plasmonic nanolaser fabrication processes, achieving high-performance sodium-based plasmonic nanolasers (Nature, 2020, 581, 7809, 401–405); using FIB-SID technology, they constructed three-dimensional chiral optical antennas (Advanced Materials, 2017, 1606482); and developed a dynamic reconfigurable three-dimensional metamaterial using MEMS technology (Nano Letters, 2016, 16(11), 7025-7029).
