Electrically Reconfigurable Metasurfaces Using Heterojunction Resonators
Published in Advanced Optical Materials, 2016
Abstract:
We introduce a heterojunction p–n Mie-resonant architecture that enables electrically driven free-carrier modulation of near-infrared dielectric metasurfaces. Bias-induced carrier accumulation in InSb resonators produces large refractive-index shifts, allowing dynamic beam steering and paving a route toward solid-state phased-array optics.
