Modeling of Quantum-Dot Elliptical Nanowire Single-Photon Sources

True monomode operation and polarization control capability of elliptical nanowires leads to the need of efficient solvers for open elliptical nanophotonic structures. In this contribution, a full-wave vectorial modal method for open boundary elliptical geometries is presented for designing quantum-dot elliptical nanowire structures. The method exploits symmetry properties, provides insight into the physical behavior of the system giving direct access to propagation constants and mode profiles, which will be used in the efficiency calculations of the single-photon sources.
