论文摘要
我们比较了使用一个，两个，三个和四个波导模式进行四波混合的相位匹配。为了进行比较，我们使用数值优化和生成的怠速功率的估计。我们介绍了几种模式纤维和纳米 - 折线波导的结果，并表明，对于两种波导类型，四波混合带宽和惰轮功率最适合一单模和两模式操作，而四模式的四波混合混合根本不可行。一些纳米 - 边缘波导支持三模式的四波混合，尽管带宽大大降低，并且惰轮的功率降低。
We compare phase matching for four-wave mixing using one, two, three, and four waveguide modes. For the comparison, we use numerical optimizations and an estimate of the generated idler power. We present results for few-mode fibers and nano-rib waveguides and show that for both waveguide types, four-wave mixing bandwidths and idler powers are best for one- and two-mode operation and that four-mode four-wave mixing is not feasible at all. Some nano-rib waveguides support three-mode four-wave mixing, albeit with much reduced bandwidth and reduced idler power.
