Inverse-Gaussian-Apodized Fiber Bragg Grating for Dual Wavelength Lasing
摘要：
提出并制作了一种具有反高斯切趾功能的光纤布拉格光栅。结果表明，这种光纤光栅具有易于控制的双波长窄透射峰。将这种光纤光栅滤波器安装在线性腔光纤激光器中，获得了波长间隔为0.146nm的稳定双波长输出。这为实现双波长光纤激光器的工作提供了一种简单、低成本的方法。
英文摘要：
A fiber Bragg grating (FBG) with an inverse-Gaussian apodization function is proposed and fabricated. It is shown that such a FBG possesses easily controllable dual-wavelength narrow transmission peaks. Incorporating such a FBG filter in a fiber laser with a linear cavity, stable dual-wavelength emission with 0.146 nm wavelength spacing is obtained. It provides a simple and low cost approach of achieving the dual-wavelength fiber laser operation.
