Photonic Modulation Using Antimony-Trisulphide Phase Change Huygens Metasurfaces (JTu3A.8)

Presenter: Siddharth Padmanabha, Tulane University

We design switchable antimony trisulfide (Sb2S3) Huygens metasurfaces for optical modulation. Simulation results show near 2π phase modulation with ~15dB amplitude modulation optimizable by spectral resonance tuning at near infrared wavelengths. Experimental verification is in progress.
