Abstract

We demonstrate apodized fiber Bragg gratings (FBGs) inscribed with a point-by-point (PbP) technique. We tailor the grating phase and coupling amplitude through precise control over the longitudinal and transverse positions of each laser-inscribed modification. This method of apodization is facilitated by the highly localized, high-contrast modifications generated by focused IR femtosecond laser inscription. Our technique provides a simple method for the design and implementation of PbP FBGs with complex apodization profiles.

摘要

我们展示了使用逐点写入（PbP）技术写入的啁啾光纤布拉格光栅（FBG）。我们通过精确控制每个激光写入修改的纵向和横向位置来调整光栅的相位和耦合幅度。这种啁啾方法得益于聚焦红外飞秒激光写入产生的高度局域化、高对比度的修改。我们的技术为具有复杂啁啾轮廓的 PbP FBG 的设计和实现提供了一种简单的方法。
