We report an analysis of one-dimensional rod-based photonic crystal nanocavities. These cavities offer opportunities for dielectric materials which lack a matching low-refractive index substrate or are limited in under-etching possibilities to create slab-based PhC cavities. They offer high theoretical -values exceeding 10 for transverse magnetic polarized modes with modal volumes below 2.5(/). For practical implementations, we propose embedding these structures in a low-refractive index polymer. An analysis of intentionally introduced variations in a rod diameter reveals which design directions should be followed in order to create cavities that are most robust for fabrication-induced variations.
我们报告了对基于一维棒状的光子晶体纳米腔的分析。对于缺乏匹配的低折射率衬底或在蚀刻不足可能性方面受限而无法制造基于平板的光子晶体腔的介电材料而言，这些腔提供了机会。对于横向磁极化模式，它们提供了超过10的高理论品质因数，模态体积低于2.5(λ³)。对于实际应用，我们建议将这些结构嵌入低折射率聚合物中。对棒直径有意引入的变化进行分析，揭示了为制造引起的变化创建最稳健的腔时应遵循的设计方向。
