项目摘要

In this study, we have presented a theory for the phase-only sampled FBG and demonstrate that a sampled FBG of Nchannels would require √<N> times higher the maximum refractive index-modulation than that of the single-channel FBG. A novel continuous phase-only sampling function capable of producing up to 81-channel FBG with excellent channel uniformity and high in-band energy efficiency is presented and optimized by using the simulated annealing algorithm. In order to fabricate this kind of FBGs with a conventional side-writing phase-mask technique, both the diffraction effects and fabrication tolerance of the phase-shifted phase mask have also been addressed. Compared with the numerical results, a 45-channel (spacing of 100 GHz) and, an 81-channel (spacing of 50 GHz) phase-only sampled linearly chirped FBG are successfully demonstrated.We have presented a novel method for multi-channel FBG design, which enables us to design any kind of multi-channel FBGs where the spectrum response of … More each channel could be either identical or non-identical. Particularly, 9-channel nonlinearly chirped FBG used as simultaneously dispersion and dispersion slope compensator has been demonstrated.We have demonstrated a novel method to measure the chromatic dispersion of a multi-channel fiber Bragg grating (FBG), which is based on an all-fiber asymmetrical Sagnac loop interferometer (ASLI) proposed Theoretical analyses to this proposed approach are presented in details. With this method, the chromatic dispersion and dispersion slope of a 51-channel FBG are simultaneously measured. The experimental results agree well with the ones obtained by using the general phase-shift method (PSM). This method has the advantages of simple configuration, low-cost, and high tolerance for the characteristics of FBG.We have presented a novel approach for the reflection equalization of a phase-only sampled fiber Bragg grating (FBG), where the grating is specially designed as a simultaneous dispersion and dispersion-slope compensator with channels up to 51. The sampling-function used is given with an analytical form with a linearly-chirped sampling period and is optimized by using the simulated annealing algorithm. Less
在这项研究中,我们提出了一个理论的相位只有采样光纤光栅,并证明了采样光纤光栅的N个通道将需要<N>的最大折射率调制比单通道光纤光栅的1/4高。提出了一种新的连续相位采样函数,该函数能够产生多达81个通道的FBG,具有良好的通道均匀性和高的带内能量效率,并采用模拟退火算法对其进行了优化。为了用传统的侧写相位掩模技术制作这类FBG,相移相位掩模的衍射效应和制作公差也得到了解决。通过与数值计算结果的比较,成功地设计了45通道(间距为100 GHz)和81通道(间距为50 GHz)的纯相位取样线性啁啾光纤光栅,提出了一种新的多通道光纤光栅设计方法,使我们能够设计出任何类型的多通道光纤光栅,其光谱响应 ...更多信息 每个信道可以是相同的或不相同的。提出了一种基于非对称Sagnac环形干涉仪(ASLI)的多通道光纤光栅色散测量新方法,并对该方法进行了详细的理论分析。利用该方法,同时测量了51通道光纤光栅的色散和色散斜率。实验结果与用一般相移法(PSM)得到的结果吻合得很好。该方法具有结构简单、成本低、对光纤光栅的特性有很高的容忍度等优点。本文提出了一种新的相位取样光纤光栅(FBG)反射均衡方法,该方法将FBG设计为色散和色散斜率同时补偿器,通道数可达51。所用的采样函数给出了线性啁啾采样周期的解析形式,并利用模拟退火算法进行了优化。少
