Dissipative pure-quartic soliton (DPQS) that arises from the balance of positive fourth-order
dispersion (FOD), nonlinearity, gain and loss has been proposed to generate high-energy …

The evolution of ultrafast laser technology hinges partially on the understanding of the

In this paper, we investigate the generation of supercontinuum (SC) light source based on a
highly nonlinear Germanium (Ge) doped photonic crystal fiber (HNL-GePCF) with all normal …

Specialty shape ultrashort optical pulses, and triangular pulses in particular, are of great
interest in optical signal processing. Compact fiber-based techniques for producing the …

We numerically demonstrate the existence of parabolic and rectangular self-similar
propagations of optical beams in saturable media. Rectangular selfsimilar evolution is …
