A transparent, fully integrated electrically modulated projection technique is presented based on light guiding through a thin liquid crystal layer covering sub-wavelength gratings. The reported device operates at 10 V with response times of 4.5 ms. Analysis of the liquid crystal alignment shows that director-reorientation occurs over timescales on the order of 90 µs close to the grating surface. The technology is suitable for next generation heads-up-displays and reconfigurable multilayer photonic integrated circuits.
本文提出了一种基于光通过覆盖亚波长光栅的薄液晶层进行引导的透明、完全集成的电调制投影技术。所报道的器件在10V电压下工作，响应时间为4.5ms。对液晶取向的分析表明，在靠近光栅表面的时间尺度上，液晶指向矢重排发生在约90µs的量级。该技术适用于下一代平视显示器和可重构多层光子集成电路。
