Abstract

This paper demonstrates the feasibility of a fast, Frequency-Agile, Stimuli responsive, Tunable (FAST) optical filter using a metamaterial combined with a Phase Change Material (PCM). The FAST Optical Filter (FOF) is optimized to operate in visible to near-infrared (NIR) wavelengths (380-1000 nm, or equivalent frequencies) with the capability to tune to multiple wavelengths, autonomously respond to and function with different polarizations of light and attain frequency agility using external stimuli. A first estimate of their optical performance (reflection and transmission characteristics) is investigated using the transfer matrix method. Incorporation of PCM within a metamaterial (metallo-dielectric stacks) sandwich can enable electronic tuning of the structure through application of an external voltage.
