论文摘要
耗散的Kerr-Microresonator soliton梳子（以下称为Soliton Combs）一直以紧凑的频率梳状态迅速发展。对于诸如LiDAR和光谱法的应用，梳子模式扫描具有较大范围和快速速度至关重要，需要对泵连续波（CW）激光的较大和快速频率扫描以及微孔子的共振频率。在这里，我们通过分布式反馈（DFB）激光朝着梳子模式扫描，以较大的范围和快速的速度来证明孤子梳子的产生。与常规的泵CW激光器（即外部空腔二极管激光器：ECDLS）相比，可以更大程度地扫描DFB激光器，而无需模式。 In addition, because of the fast scan speed of the DFB laser, a single soliton comb is generated simply by controlling the injection current of the DFB laser, greatly simplifying the system without having any additional optical modulators such as a carrier-suppressed single-sideband modulator (CS-SSB modulator), acousto-optic modulator (AOM), and auxiliary CW laser.
Dissipative Kerr-microresonator soliton combs (hereafter called soliton combs) has been rapidly progressing as compact frequency combs. Comb mode scanning of the soliton combs with a large range and fast speed is of paramount importance for applications such as LiDAR and spectroscopy, requiring large and rapid frequency scanning of a pump continuous-wave (CW) laser as well as resonance frequency of a microresonator. Here, we demonstrate the generation of a soliton comb by a distributed feedback (DFB) laser toward the comb mode scanning with a large range and fast speed. Compared with conventional pump CW lasers (i.e. external cavity diode lasers: ECDLs), DFB lasers can be frequency-scanned more largely and rapidly without mode-hopping. In addition, because of the fast scan speed of the DFB laser, a single soliton comb is generated simply by controlling the injection current of the DFB laser, greatly simplifying the system without having any additional optical modulators such as a carrier-suppressed single-sideband modulator (CS-SSB modulator), acousto-optic modulator (AOM), and auxiliary CW laser.
