LiNbO_3∶Fe晶体中的涡旋孤子及由它们写入波导的研究

Study of the vortex solitons and the waneguideswritten by them in LiNbO_3:Fe crystal

在LiNbO3 ∶Fe晶体中观察到由光生伏打效应实现的涡旋孤子对和涡旋孤子阵列并成功地由它们写入了圆形和椭圆形波导 .研究了涡旋孤子之间的相互作用 ,影响涡旋孤子形状的因素和实现稳定孤子的条件 .

We have observed, for the first time, a pair and an array of optical vortex solitons due to the photovoltaic effect in crystal LiNbO 3:Fe , and the circle and elliptical waveguides were written by them successfully. We study the interactions between the vortex solitons, factors of influence on their shape and conditions of realizing stable vortex solitons.
