Abstract

It has been shown numerically that coupled nonlinear Schrödinger equations describing the interaction between the left and right circular polarizations of a paraxial optical wave in a defocusing Kerr medium with an anomalous dispersion in a helical waveguide have stable solutions in the form of elongated stationary rotating bubbles with several optical vortices attached to the ends. A bubble is an arbitrarily long quasi-cylindrical three-dimensional cavity in one of the components filled with the opposite component. The transverse profile of the bubble is determined by the shape of the cross section of the waveguide, the helix pitch, the number of vortices, and the background intensity of the surrounding component rather than by the total amount of the filling component.

稳定螺旋波导轴附近的光学气泡
数值研究表明,描述在螺旋波导中具有反常色散的离焦克尔介质中的准轴向光波的左右圆偏振之间的相互作用的耦合非线性薛定谔方程,具有稳定的解,其形式为细长的静止旋转气泡,气泡的两端附有多个光涡旋。气泡是一个任意长的准圆柱形三维空腔,其中一个分量充满了相反的分量。气泡的横向轮廓由波导横截面的形状、螺旋间距、旋涡数量和周围成分的背景强度决定,而不是由填充成分的总量决定。
