摘 要: 經(jīng)過外延生長和腐蝕分離后，直徑為1~10 µm的獨立微盤激光器件分別被粘附在多模光纖的端面上。在室溫條件下采用光學(xué)泵浦，對該類器件均實現(xiàn)了脈沖和連續(xù)激射，輸出波長在1.5~1.525 µm之間，在脈沖和連續(xù)輸出下閾值泵浦能量分別為64和109 µW，激射波長隨著熱效應(yīng)增加而呈現(xiàn)紅移現(xiàn)象。該類器件在未來全光網(wǎng)絡(luò)和集成光路中具有良好的應(yīng)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.
