Abstract

The influence of the fiber geometry on the point-by-point inscription of fiber Bragg gratings using a femtosecond laser is highlighted. Fiber Bragg gratings with high spectral quality and strong first-order Bragg resonances within the C-band are achieved by optimizing the inscription process. Large birefringence (1.2x10(-4)) and high degree of polarization-dependent index modulation are observed in these gratings. Potential applications of these gratings in resonators are further illustrated.

摘要

强调了光纤几何结构对使用飞秒激光逐点写入光纤布拉格光栅的影响。通过优化写入过程，实现了在C波段内具有高光谱质量和强一阶布拉格共振的光纤布拉格光栅。在这些光栅中观察到了大双折射（1.2×10⁻⁴）和高度的偏振相关折射率调制。进一步阐述了这些光栅在谐振器中的潜在应用。
