摘要
We report a programmable phase change medium-based hyperbolic metamaterial (HMM) with emphasis on the optical response characterized by adjusting the electrical constants and/or structural parameters (such as thicknesses and/or filling fraction) of the constituent materials. The investigation reveals broad area of the type I HMM in the visible regime for the device comprising silver and stibnite mediums. The angle- and polarization-insensitive properties of the configuration demonstrate an in-band rejection of over −75 dB, tunable in the range of 0.5723 to 0.639 μm, and an 8-bit encoding bandwidth of 12 nm. Also, the study yields two distinct modulation mechanisms at the incidence angle of 62 deg, viz. a Brewster modulator in the UV regime (which solely depends on the incidence obliquity) and an angle-insensitive reflection modulator in the visible regime—the features that are programmable according to the thermal ambience.
