主 题:modulator triangular effect
摘 要:The generation of periodic triangular waveform with variable symmetrical coefficient based on a dual-parallel Mach-Zehnder modulator(DP-MZM) is demonstrated in this *** properly setting the modulation index and bias points of DP-MZM,desired symmetric/asymmetric triangular waveforms can be *** applying the generated triangular waveform into an amplitude modulator(AM),a single-period signal can be extracted to explore the optical wavelength conversion induced by the self-phase modulation(SPM) effect in a high nonlinear fiber(HNLF).Wavelength shifts of triangular waveforms with different coefficients(10%,20%,30%,40% and 50%) are *** addition,the influence of key parameters of HNLF on the wavelength conversion is analyzed in detail.
