Photons are excellent information carriers due to their speed, ability to travel through a vacuum, minimal interaction, and versatile properties like wavelength and polarization. However, photonic systems face challenges in reconfigurability, which is often inefficient, slow, and significantly more complex compared to electronic systems. Phase-change materials offer nonvolatile reconfigurability, while liquid crystals provide polarization-based control. Advances such as resonance shifts in optical cavities and field-of-view adjustments in metalenses highlight the potential of these innovations. Triplet metasurfaces can further enhance metalens functionality by enabling zoom in-and-out capabilities.
