The strategic field of renewable energy production and storage requires novel nanoscale platforms that can feature competitive solar energy conversion properties. Photochemical reactions that promote energy storage, such as water splitting and oxygen-hydrogen evolution reactions, play a crucial role in this context. Here, we demonstrate a novel photoelectrochemical device based on large-area (cm) self-organized Au nanowire (NW) arrays, uniformly coated with ultrathin TiO films.

- Recent advancements in photonic technologies highlight the importance of all-optical dynamic control for complex photonic elements, especially in integrated photonics and metasurfaces.
- The study presents a design for a two-dimensional bull's eye cavity made within a unique optically-active polymer that allows for the coupling of two surface resonant modes through free-space illumination.
- Dynamic control of resonant modes is achieved by changing the orientation of birefringence using a polarized laser, resulting in reversible shifts in resonant wavelengths across a 2 nm range.
