论文摘要
我们研究具有非本地重新定位非线性反应的列液晶中明亮光学涡流孤子子的传播动力学。我们研究了光学双折射对这些孤子稳定性的作用。与最近的实验观察一致，我们表明，双折射诱导的散光最终会破坏这些涡旋孤子的稳定。但是，对于低和中度的双折射，涡旋孤子可以在实验相关的距离上稳定地传播。
We study the propagation dynamics of bright optical vortex solitons in nematic liquid crystals with a nonlocal reorientational nonlinear response. We investigate the role of optical birefringence on the stability of these solitons. In agreement with recent experimental observations, we show that birefringence-induced astigmatism can eventually destabilize these vortex solitons. However, for low and moderate birefringence, vortex solitons can propagate stably over experimentally relevant distances.
