  • 采用数值方法研究了在一个具有扩散效应的光伏光折变晶体中的非相干耦合的亮和暗光伏空间孤子对的偏转特性.结果表明,由于非相干相互作用,晶体中的一个亮孤子和一个暗孤子互相俘获,且两个孤子的中心沿着相同的轨迹移动.发现,当亮孤子的入射峰值强度不变时,通过调节暗孤子的入射背景强度可以控制亮孤子的偏转;当暗孤子的入射背景强度处于一个特殊值时,亮孤子的偏转被抑制,而当暗孤子的入射背景强度偏离这个特殊值时,亮孤子发生偏转.同样,当暗孤子的入射背景强度不变时,其偏转可以通过调节亮孤子的入射峰值强度来控制.
    We numerically investigate the deflection characteristics of incoherent coupled bright and dark photovoltaic spatial soliton pairs in a photovoltaic photorefractive crystal with diffusion effect. The numerical results show that, owing to the incoherent interaction, a bright soliton and a dark soliton in the crystal trap each other and the centers of the two solitons move along the same trajectory. It is found that, the deflection of the bright soliton can be controlled by adjusting the input background intensity of the dark soliton when the input peak intensity of the bright soliton is fixed; and the deflection of the bright soliton is suppressed when the input background intensity of the dark soliton is at a special value, while the bright soliton undergoes a deflection when the input background intensity of the dark soliton deviates from this special value. Also, the deflection of the dark soliton can be controlled by adjusting the input peak intensity of the bright soliton when the input background intensity of the dark soliton is fixed.
