中文摘要：

一个有效理论分析方法被介绍分析不同线性光信号处理功能，光过滤器在文学报导了。为不同应用程序，光过滤器应当独立操作信号的模拟或数字的部分，也就是模拟的光谱变换和数字光谱变换。例如，到为调制的紧张或阶段的格式变换表明的 non-return-to-zero ( NRZ )的 return-to-zero ( RZ )基于模拟光谱变换过程，当时(N) RZ 到(N) RZ phase-shift-keying ( PSK )格式变换，不，为 RZ 的门和钟恢复表明的逻辑基于数字光谱变换进程。在数字模拟的帮助下的理论分析被用来验证报导试验性的结果，并且所有试验性的结果能有效地与这个分析模型一起被分析。变换信号的表演上的过滤器的传播光谱的效果被调查。最重要的因素是理论分析提供一个有效方法为不同光信号处理功能优化光过滤器。

英文摘要：

An effective theoretical analysis method is presented to analyze different linear optical signal processing functions with optical fikers reported in literatures. For different applications, the optical filters are supposed to operate on the analog or digital part of the signal separately, namely analog spectrum conversion and digital spectrum conversion. For instance, the return-to-zero （RZ） to non-return-to-zero （NRZ） format conversion for intensity or phase modulated signals are based on the analog spectrum conversion process, while the （N）RZ to （N）RZ phase-shift-keying （PSK） format conversion, logic NOT gate and clock recovery for RZ signals are based on the digital spectrum conversion process. Theoretical analyses with the help of numerical simulation are used to verify the reported experimental results, and all the experimental results can be effectively analyzed with this analytical model. The effect of the transmission spectrum of the filter on the performance of the converted signal is investigated. The most important factor is that the theoretical analysis provides an effective way to optimize the optical filter for different optical signal processing functions.
