摘 要: 经过外延生长和腐蚀分离后，直径为1~10 µm的独立微盘激光器件分别被粘附在多模光纤的端面上。在室温条件下采用光学泵浦，对该类器件均实现了脉冲和连续激射，输出波长在1.5~1.525 µm之间，在脉冲和连续输出下阈值泵浦能量分别为64和109 µW，激射波长随着热效应增加而呈现红移现象。该类器件在未来全光网络和集成光路中具有良好的应用前景。

Abstract:Separate microdisk laser with diameters of 1−10 µm were attached at the facet of multi-mode fiber after epitaxial growth and etching. They were all lasing under both pulsed and countinuous wave (CW) optical pumping. The lasing wavelengths were between 1.5 and 1.525 µm. The threshold pump powers were 64 µW in pulsed operation and 109 µW in CW operation separately. Lasing wavelength shows red shift with increasing thermal effect. This device has exciting applications in future all optical networks and integrated optical circuits.
