摘要

基于液晶/聚合物光栅, 以MDMO-PPV为增益介质, 在抽运增益介质层不同位置处对出射激光波长进行粗略调谐, 通过施加外部电压对出射激光波长进行精密调谐, 最终得到调谐范围为18 nm、可连续精密调谐的液晶/聚合物光栅有机半导体激光器。该研究可为改进可调谐分布反馈有机半导体激光器提供一些新思路。

Abstract

Based on the liquid crystal/polymer grating and with MDMO-PPV as the gain medium, the emission wavelengths at different positions of the gain medium layer can be roughly modulated and then precisely tuned by applying an external electric field. A continuous fine-tuning organic semiconductor laser with a tuning range of 18 nm is finally obtained based on the liquid crystal/polymer grating. This study provides some new ideas for the improvement of a tunable distributed feedback (DFB) organic semiconductor laser.
