自相位调制对超短脉冲在准周期Fibonacci光学超晶格中传输的影响
Ultra-short Pulse Propagation through a Fibonacci Quasi-periodic Optical Superlattice Influenced by Self Phase Modulation
【摘要】 从准周期Fibonacci超晶格的结构特点和超短脉冲的传输特性出发,分析了超短脉冲在Fibonacci超晶格中传输时,自相位调制对脉冲频谱的调制,同时考虑了由SPM造成的频率啁啾对脉冲特性的影响,发现SPM对脉冲特性影响很大,它不但使脉冲频谱展宽,而且限制超晶格的总体长度及基本单元的结构。
【Abstract】 In this paper, based on the structural feature of the Fibonacci optical superlatticeand the propagating characteristics of the ultra-short pulse, the spectrum modulated by SPMand influenced by chirp based on SPM is studied. The results confirm that the spectrum isbroadened, and the total length of the optical superlattice is confined by SPM.
