| 摘 要： | 为了将光码分多址(OCDMA)系统的光源与编解码器频谱相匹配,根据等效相移原理提出并实现了一种编码频谱可控的基于超结构光纤光栅的光码分多址时域相位编/解码器.该编/解码器在制作过程中仅需一块均匀相位掩模板即可在不同的目标信道上实现编码,从而为OCDMA系统与WDM(wavelength-division multiplexing)的结合提供了一个简单有效的方法.利用计算机仿真和实测数据对该编/解码器性能进行了验证.结果表明:与传统的等效相移编解码器相比,该编解码器具有更大的最佳自互相关峰值旁瓣比(P/W和P/C);在窄脉冲入射的条件下,该编/解码器具有明显的性能优势;随着脉冲宽度的增加,该编解码器性能与传统的等效相移编解码器趋于一致.

| Abstract: | In order to match the optical source with the en/decoder in the Optical Code Division Multiple Access(OCDMA) system,a new SSFBG-based OCDMA temporal phase en-decoder was proposed and realized according to the equivalent-phase-shift theory.During fabrication,only one uniform phase mask board was needed to achieve en-decoding with different target channels. Computer simulations and measured data were implied to verify the performance of the en-decoder.Results show that compared with the traditional en-decoder... |
