Active Multi-Spectral Nanophotonic Systems(WP tracking #23-000004332)
Abstract
The objective of this research is to develop the foundation for extreme and multi-spectral reconfigurability of optical response inmaterial systems whose properties can be actively tuned by external control input. The capability to synthesize active nanophotonicmaterials that can emulate and adapt between a manifold of complex spectral profiles#with high fidelity and over a broad bandwidth#could have a far-reaching impact but current nanophotonic approaches are ill-suited for this task. Approach: To address this challenge, our comprehensive approach will integrate analytical theory, numerical simulations, nanofabrication, and optical measurements. Specifically, we will develop a new design framework to synthesize tunable multi-spectral nanophotonic structures, apply this framework to realize novel families of metasurfaces with active individual unit cells, and demonstrate multispectral devices capable of probing resonant interactions beyond existing limits. Overall Merit and ONR Mission/Relevance: This research will advance the fundamental understanding of light-matter interactions in tunable nanophotonic settings and will lead to devices with record multi-spectral reconfigurability. The gained knowledge promises to be essential for novel electromagnetic functionalities relevant to the Navy and the DoD at large, in areas of sensing, navigation, and signature management.
