Femtosecond Laser Fabricated Apodized Fiber Bragg Gratings Based on Energy Regulation
In this paper, an energy regulation method based on the combination of a half-wave plate (HWP) and a polarization beam splitter (PBS) is proposed for the fabrication of apodized fiber gratings, which can effectively improve the side lobe suppression ratio of high-reflectivity fiber Bragg gratings (F...
