Study of the vortex solitons and the waneguideswritten by them in LiNbO3:Fe crystal
LiNbO2∶Fe晶体中的涡旋孤子及由它们写入波导的研究

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.
