We report an experimental study of discrete gap solitons in binary arrays of optical waveguides. We observe self-focusing indicating soliton generation when the inclination angle of an input beam is slightly above the Bragg angle and show that the propagation direction of the emerging gap soliton is influenced by the effect of interband momentum exchange.
我们报告了一项关于光波导二元阵列中离散间隙孤子的实验研究。当输入光束的倾斜角略高于布拉格角时,我们观察到了表明孤子产生的自聚焦现象,并表明出现的间隙孤子的传播方向受带间动量交换效应的影响。
