Research on chiral optics and structured light manipulation mainly focuses on the precise control of the polarization, phase, orbital angular momentum and chiral degrees of freedom of light. By utilizing micro-nano structures such as photonic crystals and metasurfaces, this research field realizes circular polarization selection, enhanced chiral response, vortex beam generation, vector optical field regulation and multi-degree-of-freedom beam shaping, which provides novel manipulation methods for chiral sensing, optical communication, quantum optics and integrated photonic devices.

Chiral Photonics and Structured Light Manipulation

This research direction mainly focuses on the regulation laws of optical fields in micro-nano optical structures. By designing the geometric structures, periodic arrangements and symmetries of photonic crystals and metasurfaces, it realizes the manipulation of light in terms of phase, polarization, propagation direction, localized modes and band structure characteristics. The research contents cover fundamental physical mechanisms including photonic band gaps, high-Q resonances, slow-light effects, flat bands, bound states in the continuum (BIC) modes, mode coupling and far-field radiation. It provides structural design foundations and theoretical support for application fields such as nonlinear optics, quantum light sources, chiral regulation, vortex beam generation and terahertz manipulation.

Fundamental Design and Physical Mechanisms of Photonic Crystals and Metasurfaces

This research direction mainly introduces machine learning methods into the structural design of photonic crystals and metasurfaces. By establishing the mapping relationship between structural parameters and optical responses, it realizes rapid prediction, inverse design and performance optimization of micro-nano optical structures. The research contents include spectral response prediction, mode feature recognition, structural parameter optimization, construction of metasurface unit libraries, and intelligent search for high-performance devices. This direction can break through the limitations of traditional methods such as low efficiency of parameter scanning, complex design space and long optimization cycles, and provide efficient intelligent design methods for high-Q resonance, bound states in the continuum (BIC), nonlinear enhancement, polarization regulation, vortex beam generation and terahertz device design.
