Dynamic Hybrid Metasurfaces

Sajjad Abdollahramezani et al.

Summary: This study introduces a reconfigurable hybrid metasurface platform by incorporating the phase-change material Ge2Sb2Te5 (GST) into metal-dielectric meta-atoms for active and nonvolatile tuning of properties of light. The reduced-dimension meta-atom can selectively control the hybrid plasmonic-photonic resonances of the metasurface via the dynamic change of optical constants of GST, demonstrating promising applications in high-contrast optical switching and efficient beam deflection. Findings suggest dynamic hybrid metasurfaces as compelling candidates for next-generation reprogrammable meta-optics.

All-silicon chiral metasurfaces and wavefront shaping assisted by interference

Chenglong Zheng et al.

Summary: Chiral metasurfaces exhibit different electromagnetic responses to circularly polarized light, such as circular dichroism and optical activity. A novel all-silicon chiral metasurface is proposed in this study by introducing destructive interference between achiral meta-atoms, achieving a maximum circular dichroism of 0.54 and bandwidth of 0.15 THz. Experimental results are in good agreement with simulations, and the proposed scheme can also be utilized for generating various interesting functions.

Reconfigurable all-dielectric metalens with diffraction-limited performance

Mikhail Y. Shalaginov et al.

Summary: This study introduces an active metasurface platform with all-dielectric, low-loss architecture for phase tuning in the full 2 range and diffraction-limited performance. A new design principle enables binary switching between arbitrary phase profiles for metasurfaces, along with a figure-of-merit tailored for reconfigurable meta-optics. The high-performance varifocal metalens with a record large switching contrast ratio and aberration-free, multi-depth imaging represents a key experimental demonstration of non-mechanical tunable metalens with diffraction-limited performance.

Recent advances in optical dynamic meta-holography

Hui Gao et al.

Summary: Holography is an ideal approach for future deep-immersive naked-eye display, but traditional holographic devices have shortcomings. Metasurfaces, composed of subwavelength unit cells, show great potential in manipulating light fields to overcome these drawbacks. Emerging applications of dynamic meta-holography may accelerate the development of light field manipulation and micro/nanofabrication.
