A Power-Equilibrium Tunable C+L band Erbium-doped Fiber Laser
摘要
报道了一种功率均衡的超宽带可调谐掺铒光纤激光器.该激光器采用窄线宽可调谐FP滤波器、掺铒光纤、波分复用器和耦合器构成光纤环形腔激光器,并通过部分反馈光功率自动控制,对输出激光功率进行均衡.实现了87 nm带宽(1525～1612 nm)范围内,输出激光功率波动小于0.2 dB的均衡结果.输出激光3 dB线宽为0.26 nm,边模抑制比大于55 dB.
Abstract
A power-equilibrium tunable C+L band Erbium-doped fiber laser is proposed and demonstrated,Which is based on Erbium-doped fiber ring,and a FP filter incorporated with a tunable bandpass filter in the ring.At the same time,the Auto-Power-Control(APC) technique is used to proportion the output power of the laser.With wide tunable range from 1525 nm to 1612 nm,the sidemode suppression ratio of the laser is more than 55 dB.The output power variation is less than +/-0.1 dB over the running range.
