The evolution of picosecond seed pulses in the normal dispersion-flattened fiber to generate supercontinuum (SC) is investigated. The appearance of wave breaking during the process and the effect of the revealed four-wave mixing on the char acteristics o
Supercontinuum (SC) generated with all-normal dispersion (ANDi) fibers has been of special interest in recent years due to its potentially superior coherence properties when compared to anomalous dispersion-pumped SC. However, care must be taken in the design of such sources since too long pump ...
Enhanced supercontinuum generation in the normal dispersion pumping regime by seeded dispersive wave emission and stimulated Raman scattering Yi Qiun, Y.Q. Xu, Kenneth K.Y. Wong, Kevin K.

the wave vector of the incidents-polarized light interacts more with the first group of atoms since it is parallel to the interface. However, the parallel and normal components of thes-polarized light wave vector interact with both groups of atoms. Thus, the dispersion property ofs- andp-polar...
theoretically and experimentally the so-called self-induced modulational instability laser and show that the passive mode-locking mechanism that is at play in this laser relies on a dissipative four-wave mixing process that leads to generation of a dark-pulse train in the normal-dispersion regime....

Continuous-wave (cw) pumped monolithic microresonators serve as an alternative platform for comb generation through broadband four-wave mixing (FWM). With anomalous group-velocity-dispersion (GVD) and self-phase modulation (SPM), optical solutions can be generated, demonstrating broad bandwidths and ...

we report on the generation of cascaded four-wave mixing(CFWM)in a photonic crystal fiber with a high peak power picosecond pulse pumping in the normal dispersion region and a weak continuous wave seeded.We also experimentally investigate the dependence of CFWM bandwidth on the seeding wavel...
