High-speed spatial light modulators that can replace conventional liquid crystal on silicon (LCoS) and digital micromirror devices (DMDs) are highly anticipated for a wide range of photonic applications. Recently, electro-optic metasurface modulators based on organic electro-optic (OEO) materials and nanostructured resonators have attracted growing attention. However, previous devices typically require driving voltages exceeding 10 V to achieve sufficient modulation, posing a major barrier to practical use. In this study, we propose a silicon-organic-hybrid optical metasurface modulator that operates at low voltage and experimentally demonstrate its high-efficiency, high-speed modulation performance.
