论文摘要
基于光子综合电路的可见光具有广泛的可调性和高相干性，这对于在生物探测，精度计量学和量子技术中的应用非常感兴趣。在这里，我们介绍了在可见光谱范围内的杂化二极管激光器的首次演示。使用基于微孔谐振器的ALGAINP光学放大器耦合到低损耗SI3N4反馈电路，我们获得了10.8 nm的光谱覆盖率，约为684.4 nm波长，高达4.8 mW输出功率。测得的内在线宽为2.3 $ \ pm $ 0.2 kHz。
Generating visible light with wide tunability and high coherence based on photonic integrated circuits is of high interest for applications in biophotonics, precision metrology and quantum technology. Here we present the first demonstration of a hybrid-integrated diode laser in the visible spectral range. Using an AlGaInP optical amplifier coupled to a low-loss Si3N4 feedback circuit based on microring resonators, we obtain a spectral coverage of 10.8 nm around 684.4 nm wavelength with up to 4.8 mW output power. The measured intrinsic linewidth is 2.3$\pm$0.2 kHz.
