| 摘 要： | 研究了功率控制的强非局域空间光孤子短程相互作用.由动量守恒,两个孤子短程相互作用时,孤子的质心轨迹因相位差而发生偏转.实验上证实了偏转幅度与功率比有关,当功率相等时,偏转最大.利用功率对相互作用的调控的特性,测量了液晶分子对光场的响应时间,发现比其对偏置电压的响应时间短很多.

| Abstract: | We investigate the power controlled short-range interactions between spacial optical solitons in the strongly nonlocal nonlinear media. For the short-range interactions, the trajectory of mass center of solitons will deflect because of the phase difference under the condition of momentum conservation. We verify by experiment that the degree of deflection depends on the ratio of the power of two solitons, and the case of equal power corresponds to the maximum deflection. Using the characteristics of power control on the interaction between solitons, we measure the photic-induced response time of nematic liquid crystals, and find that it is much shorter than the bias-voltage-induced response time. |
