Abstract
Herein, we examine a tunable phase-change material (PCM) metasurface that features an active switchable optical response, facilitating the excitation of electric dipole resonances within the visible wavelength spectrum. The tunability of this metasurface is realized by combining a PCM with a flexible polydimethylsiloxane (PDMS) substrate exhibiting a two-dimensional configuration. By adjusting the mechanical strain of the PDMS substrate, we can actively influence the near-field interactions among the resonant dielectric components, resulting in a broad spectrum of color changes. Furthermore, the overall color spectrum of the reflected light can be dynamically switched through the Sb2S3 amorphous-to-crystalline transition. This study highlights the constraints of traditional solid dielectric designs and provides novel perspectives and approaches for the advancement of tunable optical materials and devices.
