Optics

Optical direction focuses on exploring novel physical properties and prototype devices of light-matter interactions at multiple spatial and temporal scales, and developing basic research on optical microcavities and metamaterials to control and enhance light-matter interactions and to manipulate the properties of the bending space light field. Wecommit to understanding the complex light-matter interactions from microscopic (10-9m) to macroscopic (10m) scales, from continuous to ultrafast (10-18s) time scales, from classical to quantum physics, and exploring the structure of Maxwell's and Schrodinger equations in different systems.

Research fields include: the light-matter interaction in semiconductor microcavities and quantum chaos in solid environments; the far- and near-field characteristics after the interaction of metal nanostructures with light; the optical fieldcontrol of photon orbital angular momentum, nonlinear optics and quantum optics; the ultrafast optical technology with two-dimensional material; physical effects in two-dimensional material-microcavity exciton polariton; atomic and molecular interaction physics in femtosecond strong laser field and ultrafast control.
