Generation of High-order Group-velocity-locked Vector Solitons

TL;DR

This paper presents numerical simulations demonstrating the generation of high-order group-velocity-locked vector solitons with complex pulse structures and phase differences, expanding understanding of soliton dynamics in optical fibers.

Contribution

It introduces a method to generate high-order GVLVS with customizable pulse widths, intensities, and phase differences based on fundamental GVLVS configurations.

Findings

High-order GVLVS can have two-humped and single-humped pulses.

Phase difference between pulses can be 180 degrees.

Different types of high-order GVLVS (1+2, 2+2) can be achieved.

Abstract

We report numerical simulations on the high-order group-velocity-locked vector soliton (GVLVS) generation based on the fundamental GVLVS. The high-order GVLVS generated is characterized with a two-humped pulse along one polarization while a single-humped pulse along the orthogonal polarization. The phase difference between the two humps could be 180 degree. It is found that by appropriate setting the time separation between the two components of the fundamental GVLVS, the high-order GVLVS with different pulse width and pulse intensity could be obtained. 1+2 and 2+2 type high-order GVLVS could be either obtained.
