论文摘要
基于纤维的多波长激光器在电信和气象学中具有多种重要应用。我们通过实验研究具有整合的Erbium掺杂纤维（EDF）的纤维环光激光器。输出光谱是根据EDF温度的函数测量的。我们发现，低于$ 10 \ unit {％k} $的临界温度以下，测得的光谱显示出一系列狭窄且不相等的峰。讨论了峰的波长与质数序列之间的有趣联系。探索了将梳形成归因于互轴耦合的假设。
Fiber-based multi-wavelength lasers have a variety of important applications in telecommunication and meteorology. We experimentally study a fiber loop laser with an integrated Erbium doped fiber (EDF). The output optical spectrum is measured as a function of the EDF temperature. We find that below a critical temperature of about $10\unit{% K}$ the measured optical spectrum exhibits a sequence of narrow and unequally-spaced peaks. An intriguing connection between the peaks' wavelengths and the sequence of prime numbers is discussed. An hypothesis, which attributes the comb formation to intermode coupling, is explored.
