Cavity-Tunable Exceptional Points

Platform: Non-Hermitian photonics
My role: Revision-stage experimental contribution
Status: Revision-stage study

Context: Collaborative research at SUSTech.

Research focus

This study explores the relationship between the cavity environment and exceptional-point behavior in a non-Hermitian photonic system.

Schematic of the theoretical non-Hermitian resonator chain in a tunable metallic cavity, from the collaborative manuscript, Fig. 1(a). The ±iγ labels indicate the gain and loss terms of the theoretical model.

My contribution

I participated in experimental modifications and measurements during manuscript revision. This work gave me experience with the additional experimental checks needed to support and refine a research manuscript.

Detailed results will be shared through the research publication.
