光纤布拉格光栅（FBG）通常制成10至30 mm的长度。然而，根据应用，可能需要较短的长度，特别是在用于局部检测的传感器应用中。在最常见的制作条件下，使用相位掩模方法，我们已经制作了FBG的长度范围从0.35至15毫米，使用不同的准分子激光照射时间。虽然0.35 mm长的FBG可以用超过1 h的激光曝光时间制成，但实际的最小FBG长度似乎在3 mm左右，曝光时间在3至5 min的范围内。
A fiber Bragg grating (FBG) is normally made with a length of 10 to 30 mm. Depending on the application, however, a short length may be desired, especially in sensor applications for local detection. Under the most common fabrication conditions using the phase mask method, we have fabricated FBGs with lengths ranging from 0.35 to 15 mm using different excimer laser irradiation times. Although 0.35-mm-long FBGs can be made with laser exposure times exceeding 1 h, the practical minimum FBG length appears to be around 3 mm with exposure times in the range of 3 to 5 min.
