我们展示了高性能宽带可调谐外腔激光器（ECL）与金属有机化学气相沉积（MOCVD）生长的InAs/InP量子点（QD）结构。在没有腔面涂层的情况下，法布里-珀罗（FP）激光器的3-dB光谱带宽约为10.8 nm，而ECL的调谐带宽为45 nm。结合减反射/高反射膜，获得了92 nm带宽的调谐范围，波长覆盖范围为1414 ~ 1506 nm。在大部分调谐范围内，阈值电流密度低于1.5kA/cm 2。在500 mA注入电流下，获得了6.5 mW的最大输出功率。上述结果均是在室温连续波模式下获得的。
We demonstrate high-performance broadband tunable external-cavity lasers (ECLs) with the metal-organic chemical vapor deposition (MOCVD) grown InAs/InP quantum dots (QDs) structures. Without cavity facet coatings, the 3-dB spectral bandwidth of the Fabry–Perot (FP) laser is approximately 10.8 nm, while the tuning bandwidth of ECLs is 45 nm. Combined with the anti-reflection (AR)/high-reflection (HR) facet coating, a 92 nm bandwidth tuning range has been obtained with the wavelength covering from 1414 nm to 1506 nm. In most of the tuning range, the threshold current density is lower than 1.5 kA/cm 2. The maximum output power of 6.5 mW was achieved under a 500 mA injection current. All achievements mentioned above were obtained under continuous-wave (CW) mode at room temperature (RT).
