A high-power quantum-dot superluminescent diode is demonstrated under continuous-wave operation, with an output power of 137.5 mW and a corresponding spectral bandwidth of 21 nm. This represents not only the highest output power, but also a record-high power spectral density of 6.5 mW/nm for a CW-operated superluminescent diode in the 1.1 - 1.3 μm spectral region, marking more than a 6-fold increase with respect to the state of the art. The two-section contact layout of the reported device introduces additional degrees of freedom, which enable a wide tunability of the bandwidth and power depending on the desired application. A maximum bandwidth of 79 nm was recorded, with an output power of 1.4 mW. The high-power continuous-wave operation of this device would be particularly relevant for continuous, high-speed, high-sensitivity spectroscopy, imaging and sensing applications, as well as in optical communications.
展示了一种在连续波工作模式下的高功率量子点超发光二极管，其输出功率为137.5毫瓦，相应的光谱带宽为21纳米。这不仅代表了最高输出功率，而且对于1.1 - 1.3微米光谱区域内连续波工作的超发光二极管而言，其功率谱密度达到6.5毫瓦/纳米，创历史新高，相较于现有技术提高了6倍多。所报道器件的两段式接触布局引入了额外的自由度，这使得带宽和功率能够根据所需应用进行广泛调谐。记录到的最大带宽为79纳米，输出功率为1.4毫瓦。该器件的高功率连续波工作对于连续、高速、高灵敏度光谱学、成像和传感应用以及光通信尤为重要。
