二次-三次非中心对称波导中的新型孤立波和周期波

Novel solitary and periodic waves in quadratic-cubic non-centrosymmetric waveguides

Houria Triki, Vladimir I. Kruglov

摘要:

我们提出了一个广泛的一类新的孤立波和周期波在非中心对称波导表现出二阶和三阶非线性。本文证明了具有二次和三次非线性项的广义非线性薛定谔方程的亮、灰、W型孤立波和周期波的存在性。我们还得到了控制方程的精确解析代数型孤立波,包括亮波和W形波。结果表明,潜在丰富的非线性结构集通过光波导介质的传播。由于衍射、二次和三次非线性之间的平衡,这种特殊的波形特征性地存在。

英文摘要:

We present a wide class of novel solitary and periodic waves in a non-centrosymmetric waveguide exhibiting second- and third-order nonlinearities. We show the existence of bright, gray, and W-shaped solitary waves as well as periodic waves for extended nonlinear Schrödinger equation with quadratic and cubic nonlinearities. We also obtained the exact analytical algebraic-type solitary waves of the governing equation, including bright and W-shaped waves. The results illustrate the propagation of potentially rich set of nonlinear structures through the optical waveguiding media. Such privileged waveforms characteristically exist due to a balance among diffraction, quadratic and cubic nonlinearities.
