Abstract
We report the design and fabrication of a wedge structured CLC film incorporating a spatial gradient of a chiral dopant concentration. A continuous spatial laser tuning in the broad visible spectral range with tuning resolution less than 1 nm is demonstrated, which renders a CLC-based micron-sized laser an important continuously tunable laser device.
摘要
我们报告了一种包含手性掺杂剂浓度空间梯度的楔形结构胆甾相液晶（CLC）薄膜的设计与制造。展示了在宽可见光谱范围内的连续空间激光调谐，调谐分辨率小于1 nm，这使得基于CLC的微米级激光器成为一种重要的连续可调谐激光器件。
