  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.
