摘要
利用有机共轭聚合物MEH-PPV优良的发光特性和光子晶体对光的调制特性,设计制备了有机半导体二维平板的准晶光子晶体激光器。该激光器是以MEH-PPV为增益介质,利用二维平板准晶光子晶体点缺陷和上下电极表面作为反射膜共同构建激光器的微腔,获得了具有激射效应的电抽运8重准晶垂直腔面发射激光器。该激光器的阈值电流为8 m A,激射波长为606 nm,谱线半峰全宽为0.5 nm,接近光纤光谱仪的分辨率极限。
A novel quasi-crystal microcavity slab laser is designed based on conjugated polymer MEH-PPV with excellent optical-electrical properties and the modulation of quasicrystal microcavity. The MEH-PPV is applied as the gain medium and achieve electrical-pumping 8-fold quasicrystal vertical-cavity surface-emitting laser based on the confinement of point-defect photonic crystal structure and the reflection between anode and cathode in the vertical direction. The current threshold of laser is 0.8 mA, and the lasing action occurs at λ = 606 nm with a full width at half maximum （FWHM） of 0.5 nm, limited by the resolution of the spectrometer.
