| 摘 要： | 介绍了一种用布拉格光纤光栅制作啁啾光纤光栅的方法。采用氢氟酸腐蚀布拉格光纤光栅， 使光栅的横截面沿光栅轴向逐渐变小， 然后对光栅施加１．５０ Ｎ的拉力， 在光栅轴向建立应变梯度， 制作出长１５ ｍ ｍ 、峰值反射率达９２％ 、反射半高宽为５ ｎｍ 的啁啾光纤光栅。

| Abstract: | A method for fabricating chirped fiber gratings using fiber Bragg gratings is presented. A Bragg fiber grating has been tapered by etching it in HF acid. A strain gradient along the grating was formed when a tension of 1.50 N was applied to the etched fiber grating and then a 15 mm long chirped fiber grating with a peak reflection of 92% and reflection full width at half maxmum (FWHM) width of 5 nm was fabricated. |
