This paper serves as a sequel to previously reported results on cubic-quartic solitons with complex Ginzburg–Landau equation. work is various forms of power law nonlinearity that structures the self-phase modulation. The enhanced Kudryashov's approach gives soliton solution. conservation laws are also identified for models.

Simultaneous demultiplexing and regeneration of 40-Gb/s optical time division multiplexed (OTDM) signal based on self-phase and cross-phase modulation in a dispersion shifted fiber is numerically and experimentally investigated. The optimal walkoff time between the control pulse and OTDM signal is obtained by numerical simulation. Our experiment also shows that it is an effective method for rea...
