Tunable structured light with flat optics

Ahmed H. Dorrah et al.

Summary: Flat optics, with its subwavelength resolution, ease of integration, and compact design, has become a crucial player in the field of structured light and its applications. The new generation of meta-optics can shape the light and dark features of an optical field with unprecedented complexity and multifunctionality. These advancements have the potential to revolutionize camera systems, microscopes, holography, portable devices, and wearable technology, and may also open up new possibilities in optical communications and sensing.

Dynamically tunable second-harmonic generation using hybrid nanostructures incorporating phase-change chalcogenides

Muliang Zhu et al.

Summary: This study demonstrates experimentally controllable second-harmonic generation (SHG) switches in a tunable metasurface by actively controlling the crystalline phase of germanium antimony telluride (GST). The results show that high modulation depths and resonant SHG efficiencies can be achieved by controlling the phase of GST, making these switches potentially useful for practical applications such as microscopy, optical communication, and photonic computing in the nonlinear regime.

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.

Dynamically tunable third-harmonic generation with all-dielectric metasurfaces incorporating phase-change chalcogenides

Muliang Zhu et al.

Summary: Germanium antimony telluride (GST) is a promising material for reconfiguring subwavelength nanostructures due to its strong non-volatile change of the refractive index between amorphous and crystalline states. By incorporating GST into an electromagnetically-induced-transparency-based silicon metasurface, researchers successfully demonstrated a giant third-harmonic generation (THG) switch with high modulation depth. This study shows the high potential of GST-based fast dynamic nonlinear photonic switches for real-world applications.
