Diffusion-induced deflection and the effect of two-wave mixing gain on dissipative photovoltaic solitons 总被引:1,自引:0,他引:1 下载免费PDF全文
In an open-circuit dissipative photovoltaic (PV) crystal, by
considering the diffusion effect, the deflection of bright
dissipative photovoltaic (DPV) solitons has been investigated by
employing numerical technique and perturbational procedure. The
relevant results show that the centre of the optical beam moves along
a parabolic trajectory, while the central spatial-frequency component
shifts linearly with the propagation distance; furthermore, both the
spatial deflection and the angular derivation are associated with the
photovoltaic field. Such DPV solitons have a fixed deflection degree
completely determined by the parameters of the dissipative system.
The small bending cannot affect the formation of the DPV soliton via
two-wave mixing. 相似文献
