Modulating vector bisolitons with chirped Gaussian pulse shapes

Abstract We theoretically simulate the modulation of vector bisolitons with chirped Gaussian pulse shapes at 1-μm wavelength regime, when input vector bisoliton is at the state of polarization-locking or group-velocity-locking. Through varying five soliton pulse parameters (including pulse chirp, amplitude ratio, projection angle, time delay and linear birefringence/phase difference), various kinds of vector solitons at output port can be generated, which include “3 + 3″ and “4 + 4″ pseudo-high-order vector solitons with polarization-locked, “3 + 4″ and “4 + 4″ pseudo-high-order vector solitons with group-velocity-locked. The simulations pave the way for studying the dynamics of vector bisolitons and vector soliton molecules.
