GaAs/GaAlAs Vertical Cavity Surface Emitting Lasers with Low Threshold Current
【摘要】 通过对增益波导型GaAs/GaAlAs垂直腔面发射激光器的材料生长和工艺制作的研究,实现了在室温下的脉冲激射。其激射阈值电流低达10mA,输出光功率不低于0.3mw,有的可达0.7mw以上,器件单横模、单纵模工作,线宽小于4人。
【Abstract】 By the study of material growth and device processing,the GaAs/GaAlAs vertical cavity sur faceemitting laser has been fabricated.It’s lowest threshold current under pulse condition at room temperatureis 10mA,with light output higher than 0.7mw. It works at single- transverce and single-longetudinalmodes.The emission line width is no wider than 4A.(The measurement is limited by the instrument.
