标题： Light bullets in optical tandems

摘要： 我们研究了在由不同材料贡献非线性和色散的结构中三维光子弹形成的概念，包括超材料，这些材料被充分利用以创造子弹可以形成的合适条件。 此处考虑的特定几何结构由交替的环组成，这些环由高度色散但弱非线性介质和强非线性但弱色散介质构成。 我们表明，对于广泛的参数，光子弹都可以形成。 显示英文摘要

摘要： We address the concept of three-dimensional light bullet formation in structures where nonlinearity and dispersion are contributed by different materials, including metamaterials, which are used at their best to create suitable conditions where bullets can form. The particular geometry considered here consists of alternating rings made of highly dispersive but weakly nonlinear media and strongly nonlinear but weakly dispersive media. We show that light bullets form for a wide range of parameters.
