Spatial light modulators have desirable applications in sensing and free space communication because they create an interface between the optical and electronic realms. Electro-optic modulators allow for high-speed intensity manipulation of an electromagnetic wavefront. However, most surfaces of this sort pose limitations due to their ability to modulate intensity rather than phase. Here we investigate an electro-optic modulator formed from a silicon-organic Huygens' metasurface. In a simulation-based study, we discover a metasurface design immersed in high-performance electro-optic molecules that can achieve near-full resonant transmission with phase coverage over the full 2π range. Through the electro-optic effect, we show 140 (0.79π) modulation over a range of -100 to 100 V at 1330 nm while maintaining near-constant transmitted field intensity (between 0.66 and 0.8). These results potentiate the fabrication of a high-speed spatial light modulator with the resolved parameters.
空间光调制器在传感和自由空间通信中具有理想的应用，因为它们在光学和电子领域之间创建了一个接口。电光调制器允许对电磁波前进行高速强度操纵。然而，这类大多数表面由于其调制强度而非相位的能力而存在局限性。在这里，我们研究一种由硅有机惠更斯超表面形成的电光调制器。在一项基于模拟的研究中，我们发现一种浸没在高性能电光分子中的超表面设计，它可以在整个2π范围内实现近全共振传输并具有相位覆盖。通过电光效应，我们展示了在1330nm波长下，在-100至100V的电压范围内有140°（0.79π）的调制，同时保持透射场强度近乎恒定（在0.66至0.8之间）。这些结果有助于制造具有所解析参数的高速空间光调制器。
