Tailored Apodization of Femtosecond Written Fiber Bragg Gratings by Aperture Shaping
Optica Advanced Photonics Congress 2022(2022)
摘要
We present the realization of tailored apodization profiles of femtosecond written FBGs using phase mask scanning technique with aperture shaping. By controlling the cross-sectional dimension of the refractive index modification, the spectral response is formed.
