Temporal Analysis of Open-circuit Low-amplitude Photovoltaic Spatial Solitons
开路低振幅空间光伏孤子的时间分析

The propagation properties and the evolution of intensity width under open-circuit conditions in low-amplitude regime for one-dimensional photovoltaic spatial solitons were analyzed. The results indicates that a broad soliton is generated at the beginning, and as time evolves, the intensity width of photovoltaic spatial solitons decreases monotonously to a minimum value toward steady state. The time of the whole process requiring is close to a certain value equals to the dielectric relaxation time in the absence of an illuminating field for different ratios of soliton, which are the ratio between the peak intensity of the soliton and dark irradiance. The analytical solutions of both dark and bright solitons were exhibited as time extended infinitely. Relevant examples were visualized through numerical methods.
