We report the inscription of as many as 10 superimposed Bragg gratings of high reflectivity in a 25-mm segment of fiber. Using hydrogenated boron codoped and germanosilicate fibers, we inscribed 10 superimposed gratings with reflectivities above 80% and 6 superimposed gratings with reflectivities above 98%, respectively. The superimposed gratings had unequal wavelength spacing and were written over a 20-nm wavelength span in the region of 1530 nm. The inscription of each new grating caused an increase in the FWHM linewidth of the existing gratings, while their reflectivity was unaffected.
我们报告了在一段25毫米长的光纤中写入多达10个高反射率的叠加布拉格光栅。使用氢化硼共掺杂和锗酸盐光纤，我们分别写入了10个反射率高于80%的叠加光栅和6个反射率高于98%的叠加光栅。这些叠加光栅具有不等的波长间距，并且是在1530纳米区域内20纳米的波长跨度上写入的。每个新光栅的写入都会导致现有光栅的半高宽线宽增加，而其反射率不受影响。
