In this paper we demonstrate photonic band-edge laser emission from emulsion-based polymer dispersed liquid crystals. The lasing medium consists of dye-doped chiral nematic droplets dispersed within a polymer matrix that spontaneously align as the film dries. Such lasers can be easily formed on single substrates with no alignment layers. The system combines the self-organizing periodic structure of chiral nematic liquid crystals with the simplicity of the emulsion procedure so as to produce a material that retains the emission characteristics of band-edge lasers yet can be readily coated. Sequential and stacked layers demonstrate the possibility of achieving simultaneous multi-wavelength laser output from glass, metallic, and flexible substrates.
在本文中，我们展示了基于乳液的聚合物分散液晶的光子带边激光发射。激光介质由分散在聚合物基质中的染料掺杂手性向列相液滴组成，随着薄膜干燥，这些液滴会自发排列。这种激光器可以在没有取向层的单个基板上轻松形成。该系统将手性向列相液晶的自组织周期性结构与乳液制备过程的简单性相结合，从而生产出一种保留带边激光器发射特性但易于涂覆的材料。顺序层和堆叠层展示了从玻璃、金属和柔性基板实现同时多波长激光输出的可能性。
