Optical Solitons with Cubic-Quintic-Septic-Nonic Nonlinearities and Quadrupled Power-Law Nonlinearity: An Observation

The current paper considers the enhanced Kudryashov's technique to retrieve solitons with a governing model having cubic-quintic-septic-nonic and quadrupled structures of self-phase modulation. The results prove that it is redundant to extend the self-phase modulation beyond cubic-quintic nonlinearity or dual-power law of nonlinearity.

Automated summary

The paper introduces the enhanced Kudryashov's technique to retrieve solitons with specific structures, proving that extending the self-phase modulation beyond cubic-quintic nonlinearity is unnecessary.
