Chirped optical solitons in nanofibers

Abstract

The nonlinear chirp solitons are for the first time derived in optical nanofibers, thus illustrating the set of confined structure with nontrivial phase for the model of Schrödinger–Hirota equation. The model is studied with the dispersion of self-phase and self-steeping coefficients. The results show that bright, dark and singular solitons are dependent on the pulse intensity. Additionally, the constraint settings for the existence of solitons are also fall out during the derivation.
