论文摘要
众所周知,三阶分散(TOD)永远不会允许任何非线性Schroedinger(NLS)类型系统的连续波动体验模量不稳定性(MI)。值得注意的是,我们证明了一种由TOD引起的新型MI,并在ZnCDSE/ZnSE半导体超级晶格中对Wannier Ickiton质量进行空间分散。由于TOD的非线性发展,我们还可以从数值上预测新型的Akhmedieev呼吸器和圆锥体的存在。
It is well-known that third-order dispersion (TOD) never allows the continuous wave of any nonlinear Schroedinger (NLS) type system to experience modulational instability (MI). Remarkably, we demonstrate a new kind of MI induced by TOD with spatial dispersion accounting for Wannier exciton mass in a ZnCdSe/ZnSe semiconductor superlattice. We also numerically predict the existence of novel Akhmediev breathers and Peregrine solitons due to the nonlinear development of MI with TOD.
