我们提出了通过直接构造由掺有激光染料香豆素和DCM混合物的UVII-HS抗蚀剂组成的增益介质而产生的有机光子晶体激光器的反馈结构。利用干涉光刻技术实现了光子晶体结构。这种方法大大减少了实现有机激光器反馈结构所需的步骤数量。实验得到的色散关系与计算机模拟的能带图吻合得很好。
We present feedback structures for an organic-photonic-crystal laser created by directly structuring the gain medium, consisting of UVII-HS resist doped with a mixture of the laser dyes Coumarin and DCM. The photonic-crystal structure is realized by means of interference lithography. This approach greatly reduces the number of steps required to realize the feedback structure of an organic laser. The dispersion relations obtained expermimentally agree very well with the computer simulated band diagram.
