A numerical framework to analyze the nature of guided light in waveguide quantum electrodynamics — •Christoph Martens1 and Kurt Busch1,2 — 1Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy, Max Born Str. 2A, 12489 Berlin, Germany — 2Humboldt-Universität zu Berlin, Institut für Physik, AG Theoretische Optik & Photonik, Newtonstr. 15, 12489 Berlin, Germany
Low-dimensional waveguiding structures combined with embedded single emitters are the basic building blocks of quantum-photonic circuits. The photon transport through such systems is primarily determined by strong quantum interference of single- or few-photon states caused by the restriction of the radiation to the waveguiding elements before and after the scattering. This leads to interesting transport properties, e.g. interaction–induced radiation trapping [1] or a variety of the Hong-Ou-Mandel effect [2].
In this contribution we present our numerical framework that is used to investigate the dynamics of photon transport in waveguiding systems in the presence of quantum impurities. The framework encloses multi-level atoms of different configurations as impurities, waveguides with nonlinear dispersion relations for photons, and time-dependent driving fields. With the help of this, we can monitor the evolution of certain initial few-photon states in time domain and real space to reveal and understand physical phenomena in these systems.
