双色双折射晶体中的调制不稳定性和孤子

Modulation instability and solitons in two-color nematic crystals

Theodoros P. Horikis

摘要:

本文导出了双折射晶体中两个非线性相互作用波稳定演化的条件。两种情况下被认为是:平面波和孤子。在第一种情况下,调制不稳定性分析表明,虽然非局部项抑制的增长率,基本上,耦合系统表现出显着更高的增长率比其标量对应。在孤子情况下,得到了孤子稳定、无畸变演化的必要条件,抑制了孤子的呼吸行为和辐射,导致孤子的相互导引。

英文摘要:

The conditions under which stable evolution of two nonlinear interacting waves are derived within the context of nematic crystals. Two cases are considered: plane waves and solitons. In the first case, the modulation instability analysis reveals that while the nonlocal term suppresses the growth rates, substantially, the coupled system exhibits significantly higher growth rates than its scalar counterpart. In the soliton case, the necessary conditions are derived that lead the solitons to exhibit stable, undistorted evolution, suppressing any breathing behavior and radiation, leading to soliton mutual guiding.
