Extra-cavity manipulation from traditional scalar to flexible vector solitons

Abstract

Soliton manipulation is considered as an effective way to generate complicated and controllable vector solitons. Here, we experimentally acquire flexible vector solitons deriving from standard scalar solitons by route-assisted and birefringence-enhanced structures along the laser output port. These vector solitons with weak interaction between two polarized components possess tunable pulse numbers, intensities, and intervals. These results would be a significant complement for soliton polarization dynamics as well as a valuable soliton light source for various practical applications.
