Femtosecond Laser Fabricated Apodized Fiber Bragg Gratings Based on Energy Regulation

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...
