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 the birefringence-induced astigmatism can eventually destabilize these vortex solitons. However, for low and moderate birefringence, vortex solitons can propagate stably over experimentally relevant distances.
我们研究了具有非局域重取向非线性响应的向列型液晶中亮光学涡旋孤子的传播动力学。我们研究了光学双折射对这些孤子稳定性的作用。与最近的实验观察结果一致，我们表明双折射引起的像散最终会使这些涡旋孤子失稳。然而，对于低双折射和中等双折射，涡旋孤子可以在实验相关的距离上稳定传播。
