摘要

This paper investigates the temporal behaviour of open-circuit bright photovoltaic spatial solitons by using numerical techniques. It shows that when the intensity ratio of the soliton,the ratio between the soliton peak intensity and the dark irradiance,is small,the quasi-steady-state soliton width decreases monotonically with the increase of τ,where τ is the parameter correlated with the time,that when the intensity ratio of the soliton is big,the quasi-steady-state soliton width decreases with the increase of τ and then increases with τ,and that the formation time of the steady-state solitons is not correlated with the intensity ratio of the soliton. It finds that the local nonlinear effect increases with the photovoltaic field,which behaves as that the width of soliton beams is small and the self-focusing quasi-period is short. On the other hand,we also discuss that both the time and the temperature have an effect on the beam bending.
