Spectral decoupling regulation through targeted ion migration in electro-optical resonators.

ABSTRACT: Spectral decoupling concerns about selective modulation of specific regions over the wide electromagnetic spectrum, which is highly desirable for smart handling of light/heat, such as photo-thermal regulation, multiband camouflage, etc. However, effective spectral decoupling is still lacking, especially for independent control over non-adjacent bands with orders of discrepancy in wavelengths, e.g., visible and longwave infrared (LWIR). Herein, we demonstrate spectral decoupling regulator (SDR) based on a bilayer electro-optical resonator, which can be electrochemically reconstructed by targeted ion migration into the dielectric and reflective layers, respectively. The SDR is featured by switchable color presentation and wide-range LWIR regulation (with a Δε_LWIR of 0.57), consequ
