Photon correlations in one-dimensional coupled resonator optical waveguides — •Matthias Moeferdt¹, Peter Schmitteckert², and Kurt Busch^1,3 — ¹Humboldt-Universität zu Berlin, Institut für Physik, AG Theoretische Optik und Photonik, Newtonstr. 15, 12489 Berlin, Germany — ²Institut für Nanotechnologie, Karlsruher Institut für Technologie (KIT), 76344 Eggenstein-Leopoldshafen, Germany — ³Max-Born-Institut, Max-Born-Str. 2A, 12489 Berlin, Germany

We numerically simulate the propagation of wave packets containing two photons in a one-dimensional coupled resonator optical waveguide, equipped with a side-coupled two-level system.

The two-level system causes an effective photon-photon interaction, resulting in radiation trapping in the immediate neighborhood of the two-level system, as well as strong correlations between the reemitted photons.

To study these correlations, we compute the correlation functions and employ a two-dimensional representation of the two-photon wavefunction in order to visualize the photon transport. We show that its nature depends strongly on the position of the initial pulse in the band.
