Multi-reflective peak and bandwidth scalable liquid crystal (LC) filters were investigated. By refilling a cholesteric LC (CLC) whose chiral pitch is different to the target template into a blue phase LC (BPLC) template, a multi-reflective peak single layer LC filter can be fabricated. With multiple templating and refilling processes, the number of reflective peaks can be further increased. Moreover, by refilling the CLCs of designed chiral pitch into a CLC template sequentially, a bandwidth scalable single layer CLC filter can be fabricated. The LC filters show great potential applications in optical communication, display, and LC lasing.
对多反射峰和带宽可扩展的液晶（LC）滤波器进行了研究。通过将手性间距与目标模板不同的胆甾相液晶（CLC）重新填充到蓝相液晶（BPLC）模板中，可以制造出多反射峰单层LC滤波器。通过多次模板化和重新填充过程，反射峰的数量可以进一步增加。此外，通过将设计好手性间距的CLC依次重新填充到CLC模板中，可以制造出带宽可扩展的单层CLC滤波器。这些LC滤波器在光通信、显示和LC激光发射方面显示出巨大的潜在应用。
