论文摘要
在本文中，我们介绍了一项实验研究，该研究对嵌入式计量应用的固态频率梳子的计量学稳定。梳子是一种被动模式的激光二极管，基于INGAAS/INP量子误差结构，将光学线发射到9 nm带宽中，以1.55 $ $ m $ m m的重复速率为10.09 GHz。频率稳定是通过将梳子的光学注入锁定在计量频率标准上引用的外部空腔激光二极管来实现的。一个人观察到光谱纯度从注射激光器转移到注射量的相邻模式以及稳定性向相邻模式的转移。长期稳定性的测量突出了一个被动模式锁定过程的随机行动行为，突出了频率噪声。在梳子的重复频率下，注射激光器的边带也使提出转移机制并考虑在计量稳定性水平上完全稳定频率梳子是可能的。
In this paper, we present an experimental study of the metrological stabilization of a solid-state frequency comb for embedded metrology applications. The comb is a passively mode-locked laser diode based on InGaAs/InP Quantum-dash structure emitting optical lines into a 9 nm bandwidth centered at 1.55 $μ$m with a repetition rate of 10.09 GHz. The frequency stabilization is achieved by optical injection locking of the comb with an external cavity laser diode referenced onto a metrological frequency standard. One observes the transfer of the spectral purity from the injection laser to the neighbouring modes of the injected one as well as the transfer of stability to the adjacent modes. The measurement of the long term stability highlights a frequency noise with random walk behavior specific of the passive mode locking process. Demonstration of sidebands of the injection laser at the repetition frequency of the comb also makes it possible to propose a transfer mechanism and to consider a complete stabilization of the frequency comb at a metrological stability level.
