提出了一种不使用相移掩模制作相移光纤布拉格光栅的简单方法。两个3mm长的标准光纤布拉格光栅（FBG）以相同的布拉格波长顺序刻在单模光纤中，使得FBG物理上重叠一个光栅周期。这在标准FBG的反射光谱的中间引起光谱空穴，相当于π相移FBG。在任何选择的波长写入PSFBG的技术的灵活性被证明。结果表明，用该方法制备的PSFBG器件重复性好，工艺快速。
A simple technique for fabricating phase-shifted fibre Bragg gratings (PSFBGs) without the use of a phase-shifted phase mask is presented. Two, 3-mm long, standard fibre Bragg gratings (FBGs) were inscribed sequentially in singlemode fibre at the same Bragg wavelength such that the FBGs physically overlapped by one grating period. This induces a spectral-hole in the middle of the reflection spectrum of a standard FBG, equivalent to a π-phase shifted FBG. The flexibility of the technique in writing PSFBGs at any choice of wavelength is demonstrated. The results show that PSFBG devices produced by this method are highly reproducible and the process is fast.
