We show this both for a wideband method, which can take reflections into account, and for a split-step method for the modeling of ultrashort ...

We show that the cascade is induced by a six-wave resonant interaction process and is characterized by ...

It is found that the period of such complete interband photonic transitions can be modulated for the relatively weak nonlinear effect, while ...
