| 摘 要： | 利用传输矩阵法对相移和变迹长周期光纤光栅的传输特性进行了计算和分析,提出长周期光纤光栅传输谱的相移优化设计方法.采用非均匀相移的设计思想,优化长周期光纤光栅的传输谱.和传统的均匀相移和变迹长周期光纤光栅相比,可以有效消除长周期光纤光栅谐振波长附近的旁瓣,并保证其传输性能.计算和分析结果表明:这种方法比传统的变迹优化设计方法更有效.

| Abstract: | The transmission spectrum of the phase shifted and apodized long period fiber grating with different parameters is calculated and analyzed based on the fundamental matrix approach. The design method of phase shifted optimum is given, it uses the nonuniform phase shifted method to optimize the transmission spectrum of long period fiber grating. Compared with uniform phase shifted and apodized method, this method can effectively remove the sidelobes near the resonant wavelength. The calculation and analysis results show that it is a effective design method compared with the design method of apodized optimum. |
