Abstract

A fiber Bragg grating (FBG) with an inverse-Gaussian apodization function is proposed and fabricated. It is shown that such a FBG possesses dual-wavelength narrow transmission peaks and the wavelength spacing between the two peaks is easily controllable during fabrication. Incorporating such a FBG filter into a fiber laser with a linear cavity, we obtain stable dual-wavelength emission with 0.146 nm wavelength spacing. This arrangement provides a simple and low cost way of achieving dual-wavelength fiber laser operation.

摘要

提出并制作了一种具有反高斯切趾函数的光纤布拉格光栅（FBG）。结果表明，这种FBG具有双波长窄传输峰，并且在制作过程中两个峰之间的波长间距易于控制。将这种FBG滤波器应用于线性腔光纤激光器中，我们获得了波长间距为0.146 nm的稳定双波长输出。这种方案提供了一种实现双波长光纤激光运转的简单且低成本的方法。
