利用长周期光纤光栅（LPFG）和激光诱导石墨烯加热器（LIG-H）实现了一种电调谐全光纤锁模掺铒光纤激光器。波长可调谐性是通过长周期光纤光栅的温度依赖性透射光谱实现的。中心波长可在1549.00 ~ 1563.63 nm范围内连续调谐，光谱调谐范围为14.63 nm。聚酰亚胺（PI）纸上的石墨烯是使用10.6 μ mCO 2激光器制造的，其最高工作温度约为500 ℃提出的基于长周期光纤光栅的锁模光纤激光器的电调谐提供了一种新颖的，可重复的，简单的，和成本效益的激光调谐技术。
We demonstrate an electrically tunable all-fiber mode-locked erbium-doped fiber laser using a long-period fiber grating (LPFG) assisted by laser induced graphene heaters (LIG-H). Wavelength tunability is achieved by the temperature-dependent transmission spectrum of the LPFG. The central wavelength can be continuously tuned from 1549.00 nm to 1563.63 nm with a spectral tuning range of 14.63 nm. The graphene on polyimide (PI) paper is fabricated using a 10.6 μm CO 2 laser, which has a maximum operating temperature of around 500 C. The proposed LPFG-based electrical tunability of mode-locked fiber laser provides a novel, repeatable, simple, and cost-effective laser tuning technique.
