Projects
Topological Waves
Structured waves are ubiquitous for all areas of wave physics where the wavefields cannot be approximated by a single plane wave. Topological structures and singularities of waves provide a number of nontrivial phenomena and additional functionalities as compared to a single plane wave. Topological waves underpin modern photonics, yet they are equally important, e.g., for quantum matter waves, acoustics, water waves, etc.

Angular Momentum of Structured Light
Researches involve vector vortex beams carrying spin and orbital angular momentum (OAM), topological phase, singularities splitting, structured light, etc. I specially focused on the tunable and multi-singularity structured beam, controlled by laser and digital hologram, and the applications of spin-to-orbital coupling and the quantum properties.

Quantum-Analogous Photonic System
A quintessential property of quantum systems is the non-separability of entanglement, which is not unique to quantum mechanics but found elsewhere in nature, e.g. the structured light. Exploration of multi-partite non-separable states in higher-dimensional classically entangled light enables novel quantum-classical-connected applications.

Topological Photonic Quasiparticles/Skyrmions
Skyrmions are a special type of topological particles with sophisticated spin textures in solid-state and quantum physics, but only recently being possible to be controlled in structured optical fields. The elegant vectorial structure and topological tunability of optical skyrmion meets the urgent requirements of higher-dimensional structured light.

Researches involve vector vortex beams carrying spin and orbital angular momentum (OAM), topological phase, singularities splitting, structured light, etc. I specially focused on the spectrum- and OAM-tunable vortex beams and multi-singularity structured beam and the applications of spin-to-orbital coupling and the quantum properties.

Ultrafast Nonlinear Optics
Researches includes mode-locking laser, chirped-pulse amplification (CPA), and ultrafast nonlinear fiber optics. I proposed the gain-phase modulation theory that characterizes cross-modulation between the gain and chirped phase in CPA with experimental verifications. I recently focused on ultrafast structured light and its nonlinear effects.
