About me

Jie Xu, born in 1993 in Leping, Jiangxi, obtained my bachelor's, master's, and doctoral degrees from Nanchang University in 2014, 2017, and 2020 respectively. After graduating with a Ph.D. in 2020, I joined Southwest Medical University. My main research topics include theoretical studies on magneto-optical heterostructures and their applications in subwavelength and deep-subwavelength functional devices, slow light, metamaterials, extraordinary optical transmission, and near-zero index mode/material research. My recent research focuses on the design and implementation of all-optical logic gates using magneto-optical heterostructures.

Research Focus

• MO one-way waveguide：In MO systems, EM waves exhibit nonreciprocal propagation characteristics due to the presence of an external magnetic field or magnetization. Leveraging this nonreciprocity, I have designed several one-way structures that can be used to achieve special optical functional devices, such as trapping and releasing EM waves, as well as optical switches and buffers.

• INZ theory and its applications：Index-near-zero (INZ) modes are extensively researched in epsilon-near-zero (ENZ) materials. Their near-zero phase shift makes them ideal for applications such as optical cloaking.

• All-optical logic operations：The electric logic operations are suffering from the dramatically enhanced crosstalk and energy loss in the microcomputers. The optical computation based on the all-optical logic gates are believed to be a potential solution.
