Using the numerical solution of the nonlinear Schrödinger equation and a variational method, it is shown that ( 3+1 ) -dimensional spatiotemporal optical solitons, known as light bullets, can be stabilized in a layered Kerr medium with sign-changing nonlinearity along the propagation direction.
通过使用非线性薛定谔方程的数值解和变分方法，结果表明，在沿传播方向具有符号变化非线性的分层克尔介质中，被称为光子弹的（3 + 1）维时空光学孤子可以被稳定。
