摘要：

This paper examines how a complete photonic band gap in a semiconductor nanowire superlattice can be achieved. By choosing the nanowire superlattice periodicity and its radius, a photonic band gap can be localized below the single optical mode cut-off frequency of the nanowire waveguide. We show that Bragg mirrors with near-unity reflectivity as well as high quality factor single defect cavities can be designed in a nanowire even by using dielectric stack materials with a low index contrast.
