Overview

This research demonstrates improved Q-factors in optical antennas using epsilon-near-zero materials, highlighting dynamic reconfigurability and enhanced light-matter interactions.

Key Points

Significantly enhanced Q-factors exceeding 100 were achieved through the embedding of Mie resonators in epsilon-near-zero media, improving light-matter interactions.
Three resonator configurations were introduced, including voids in AlN and intrinsic InSb in doped InSb, showcasing versatility for various optical applications.
Dynamic reconfigurability was demonstrated in intrinsic InSb resonators by thermally tuning the ENZ wavelength over a range of 2 μm in the mid-infrared wavelength regime.
These findings advance the use of high-Q optical devices for applications in high-fidelity sensors and reconfigurable metasurfaces, while addressing fabrication challenges.
