Overview

Observational analysis reveals improved dual-polarization beam steering in a Sb2Se3 metasurface, suggesting advances in optical sensing.

Key Points

  • The design achieves a beam steering angle of up to 65˚ and a minimum reflectance of 53%, enhancing LiDAR performance.
  • At a wavelength of 1550 nm, the metasurface enables dynamic phase modulation across a wide range, indicating robustness.
  • Employing voltage-controlled Joule heating, the metasurface facilitates phase transitions in Sb2Se3, improving control.
  • The introduction of air-gap structures effectively suppresses thermal crosstalk, highlighting a significant design innovation.
