In this paper, we demonstrate a holographic polymer-stabilized blue-phase liquid crystal grating fabricated using a visible laser. As blue phase is stabilized by the interfered light, polymer-concentration gradient is achieved simultaneously. With the application of a uniform vertical electric field, periodic index distribution is obtained due to polymer-concentration gradient. The grating exhibits several attractive features such as polarization-independency, a broad temperature range, sub-millisecond response, simple fabrication, and low cost, thus holding great potential for photonics applications.
在本文中，我们展示了一种使用可见激光制造的全息聚合物稳定蓝相液晶光栅。由于蓝相通过干涉光得以稳定，同时实现了聚合物浓度梯度。施加均匀垂直电场后，由于聚合物浓度梯度而获得周期性折射率分布。该光栅具有诸如偏振无关性、宽温度范围、亚毫秒响应、制作简单和成本低等几个吸引人的特性，因此在光子学应用中具有巨大潜力。
