摘要

摘要 在具有反常色散的离焦克尔介质中,具有两个圆偏振光的准轴向光学耦合非线性薛定谔方程,在形式上与冷原子的二元玻色-爱因斯坦凝聚态(BEC)的格罗斯-皮塔耶夫斯基方程相吻合。在这种情况下,光波导的螺旋对称性对应于限制 BEC 的横向势能的旋转。离心力 "极大地影响了光波在这种系统中的传播。对具有椭圆截面的波导进行的数值实验揭示了由量子化涡旋和两个极化之间的畴墙组成的特征结构,这在光学领域是前所未有的。

An Optical Analog for a Rotating Binary Bose—Einstein Condensate

An Optical Analog for a Rotating Binary Bose—Einstein Condensate

An Optical Analog for a Rotating Binary Bose—Einstein Condensate

Coupled nonlinear Schrödinger equations for paraxial optics with two circular polarizations of light in a defocusing Kerr medium with anomalous dispersion coincide in form with the Gross–Pitaevskii equations for a binary Bose—Einstein condensate (BEC) of cold atoms in the phase separation regime. In this case, the helical symmetry of an optical waveguide corresponds to rotation of the transverse potential confining the BEC. The “centrifugal force” considerably affects the propagation of a light wave in such a system. Numerical experiments for a waveguide with an elliptical cross section have revealed characteristic structures consisting of quantized vortices and domain walls between two polarizations, which have not been observed earlier in optics.
