| 摘 要： | 为了增加可调谐光纤激光器的调谐带宽,需要一种具有大信道间隔、大的总带宽、各信道的峰值反射率在带内保持均匀而在带外迅速下降的多信道滤波器.提出了一种基于光纤光栅大信道间隔的多信道滤波器实现方法,采用了振幅采样结合相位采样的线性啁啾光纤光栅,基于矩形函数的采样形式,不需要作单个采样的切趾.用所提出方法可以实现一块模板设计任意信道间隔的光纤光栅.通过理论和实验结果的对比,该设计方法得到很好的验证.

| Abstract: | In order to increase the bandwidth of tunable fiber laser, a large channel spacing and bandwidth multi-channel filter with same reflection peak is required. Arealization method of a multi-channel filter based on large channel spacing linear chirped fiber grating has been presented, which applies amplitude and phase samplings and is based on rectangle function sampling form without apodization. Any channel spacing fiber grating can be realized in one phase mask by this method. Through the comparison of theory design and experiment result, the design method is well confirmed. |
