摘要
利用传输矩阵法分析了相移光纤光栅的特性,导出了反射率理论表达式,并讨论了光栅反射谱中透射峰与相移量、相移区位置以及光栅的参数的变化关系。
The characteristics of phase-shifted fiber Bragg grating are analyzed by use of transfer matrix formulation and the theoretical expression of reflectivity is p resented. The influences of magnitude and location of the phase-shift region an d the parameters of a grating on the narrow transmission peak in reflection spec tra of the grating are discussed.
