Tunable VO2 Cavity Enables Multispectral Manipulation from Visible to Microwave Frequencies
Optical materials capable of dynamically manipulating electromagnetic waves are an emerging field in optics. However, the multispectral manipulation based on these materials is challenging due to their ubiquitous wavelength dependence. Scientist in China and Singapore cascaded VO2-based tunable optical cavities with selective-transparent layers, realizing the multispectral manipulation with reversible tunability covering wavelengths ranging from the visible to microwave regions. This work will provide a critical approach for expanding the multispectral manipulation ability of optical systems.
