本文给出了量子点垂直腔面发射激光器在室温下连续波基态激光特性的实验数据。在10 μ m直径的氧化物孔径下，采用三层有源区，获得了703 μA的阈值电流，激射波长为1.06 μm。在2 μ m2的小孔径下，获得了阈值电流为268 μA的激光输出。的阈值条件进行了讨论，强调自发和受激衰减率由于共振激发。
Data are presented on the room-temperature, continuous-wave ground state lasing characteristics from a quantum dot vertical-cavity surface-emitting laser. A threshold current of 703 μA is obtained for a 10-μm-diameter oxide aperture using a three-stack active region, with the lasing wavelength of ∼1.06 μm. Lasing is obtained for apertures as small as 2 μm square with threshold current of 268 μA. The threshold conditions are discussed with an emphasis on the spontaneous and stimulated decay rates due to resonant excitation.
