Tunable Photonics

A significant part of modern meta-optical structures is inherently designed as static: their functionality is fixed during fabrication. Tunable photonics changes this paradigm, transforming metadevices from disposable optical elements into reprogrammable components capable of dynamically altering their response.

We explore various approaches to changing the response of photonic structures: reversible and irreversible modifications, fast nonlinear and relatively slow mechanisms based on phase transitions, volatile and nonvolatile switching, and combinations of these strategies. Our research is aimed at creating active metasurfaces, tunable metadevices, and adaptive optical systems capable of changing their focus, beam direction, polarization response, and spectral properties in real time.
