摘要 对部分空间非相干光光生伏打暗空间孤子进行了实验研究.在光折变晶体L iN bO3:F e中,分别观察到由相位掩模和振幅掩模产生的部分空间非相干光光生伏打暗空间孤子及其感应波导,并且由两个部分空间非相干光光生伏打暗空间孤子感应的波导制成定向耦合器,研究了耦合效率与空间孤子之间距离的关系. An experiment of partially spatially incoherent photovoltaic dark spatial soliton is presented. We have observed partially spatially incoherent photovoltaic dark spatial solitons initiated from a phase mask and an amplitude mask, respectively, and the waveguides induced by them in a LiNbO3:Fe crystal. We have also realized a directional coupler formed by the waveguides induced by two partially spatially incoherent photovoltaic dark spatial solitons, and studied the relationship between the coupling efficiency and the distance.
