Abstract

This document describes a modal method for optical simulations of structures with elliptical cross sections and its application to the design of the photonic nanowire (NW)-based single-photon source (SPS). The work was carried out in the framework of the EMRP SIQUTE project ending May 31st 2016. The document summarizes the new method used to treat the elliptical cross section in an efficient manner and additionally presents design parameters for the photonic NW SPS with elliptical cross section for polarization control. The document does not introduce the new method and the elliptical photonic NW SPS design in the context of existing literature but instead dives directly into the equations. Additionally, the document assumes that the reader possess expert knowledge of general modal expansion techniques. The presented formalism does not implement Li's factorization rules nor the recently proposed open boundary geometry formalism with fast convergence towards the open geometry limit but instead relies on (older) formalism based on coordinate transformations for emulating open systems. However, the document does contain all the information needed for the expert reader to implement the method and reproduce the simulations.
