振幅调制的色散振荡光纤对流氓波的控制(特邀)

Control of Rogue Wave by Amplitude Modulated Dispersion Oscillating Fiber(Invited)

中红外超连续谱光源具有超宽频谱、高相干和高亮度等特点,在很多领域都有着广泛的应用。但是在超连续谱的产生过程中,调制不稳定性会使不同基阶孤子之间的能量发生转移,形成光学流氓波。它是一种具有超高强度、极大红移并产生在超连续谱长波长处的低概率事件,它的产生严重影响超连续谱的性能。所以对于光学流氓波控制的研究,就变成了一个热点话题。由于色散振荡光纤具有灵活可调的色散和非线性,可以有效控制光学流氓波的产生,所以,主要研究中红外超连续谱中色散振荡光纤对光学流氓波的作用。

Mid infrared supercontinuum light source has the characteristics of ultra-wide spectrum,high coher-ence and high brightness,which is widely used in many fields.However,in the process of supercontinuum genera-tion,modulation instability causes the transfer of energy between different fundamental solitons to form optical rogue waves.It is a low probability event with ultra-high intensity,great red shift and produced at the wavelength of supercontinuum spectrum.Its generation seriously affects the performance of supercontinuum spectrum.Therefore,the research on optical rogue wave control has become a hot topic.Because the dispersion oscillating fiber has flexi-ble and adjustable dispersion and nonlinearity,which can effectively control the generation of optical rogue wave.Therefore,the effect of dispersion oscillating fiber on optical rogue wave in mid infrared supercontinuum spectrum is mainly studied.
