Semiconductor Laser with Weak Coupling Fiber Grating External Cavity
摘要
报道作者对单频窄线宽光纤光栅外腔半导体激光器的一些研究结果。理论上分析了外腔的引入对激光器的阈值增益和光谱线宽的影响;实验上用自行研制的光纤布拉格反射滤波器(FBR)与普通多纵模半导体激光器耦合,在1.55 μm波段,得到边模抑制比大于25 dB,线宽小于60 kHz的激光输出。
Abstract
Some results of our study on single frequency, narrow linewidth fiber grating external cavity semiconductor laser are reported in this paper. The effects of external cavity feedback on the threshold gain and emission linewidth are discussed theoretically; Laser emission with side mode suppression ratio more than 25 dB, spectrum linewidth narrower than 60 kHz is realized at 1.55 μm wavelength region experimentally by coupling a conventional multimode semiconductor laser with a fiber Bragg reflective (FBR) filter fabricated by ourselves.
