摘要
在考虑自相位调制和高阶群速色散的情况下,分析了超短脉冲在准周期Fibonacci超晶格中传输时,入射光强对脉冲传输特性的影响.结果表明:入射光强度对脉冲传输特性影响很大,不但使频谱展宽,而且限制超晶格的有效长度,是超短脉冲进行频率转换的主要考虑因素之一.
Abstract
In this paper, taking into account both the self-phase-modulation (SPM) and the lowest and second order group velocity dispersion (GVD), the propagation equations of ultra-short pulses is given through numerical analysis. The influence of input intensity on ultra-short pulses in Fibonacci super-lattice is analyzed. The calculations show that the input intensity cause broadening in the spectrum and set a limit to effective length of super-lattice, which is an important factor for frequency conversion
