摘要
使用二次曝光法或相位掩膜法制作的相移光纤光栅,可在光纤光栅阻带中打开一个狭窄的透射窗口,窗口位置可以随着相移量的大小发生改变。利用传输矩阵法的计算,对相移光纤光栅的反射光谱特性进行了分析,并且对如何利用相移光纤光栅的光谱特性进行多方面的应用给予了展望。这些结果将对相移光纤光栅的实际制作及应用有重要的指导意义。
Phase shifts written by UV post- processing or using a phase mask, open up narrowband transmission windows inside the stop band of the Bragg grating; Transmitted wavelength can be changed by adjusting the amount of phase shifts. Based on the transfer matrix approach, the main reflective spectra character of phase - shifted fiber grating and their applications are analyzed. These theoretical results have important signif- icance for actual application and fabrication of the phase shifted fiber gratings.
