摘要
利用准分子激光振幅掩膜调制曝光技术，制出了周期为４００μｍ的长周期光纤光栅．通过对其透射光谱测试，观察到它在１．５０μｍ附近具有四个吸收峰，峰值中心位置分别为１．４６５μｍ，１．４８０μｍ，１．５０８μｍ和１．５２５μｍ，平均半高宽约１５μｍ．
The hydrogen doping fiber was exposed to modulated excimer laser beam by using a amplitude mask. Then long-period fiber gratings with 400 μm period were obtained. By measuring its transmit spectrum, we found that there were four absorption peaks at 1. 465μm, 1. 480μm, 1.508μm and 1.525μm respectively. The average full width at half maximum is about 15 nm.
