Coupling of quantum emitters to localized photonic modes in disordered structures — •Patrick Folge, Mohsen JaniPour, Ruben Pompe, Felix Fenner, and Walter Pfeiffer — Fakultät für Physik, Universität Bielefeld, 33615 Bielefeld, Germany

We investigate the coupling between quantum emitters to localized photonic modes in disordered dielectric waveguide structures. Localization of electromagnetic fields facilitates enhanced light matter interaction as it is commonly used in photonic crystal cavities. Periodic placement of holes in a two-dimensional waveguide forms photonic crystals with photonic band gaps that enable the formation of defect induces localized modes. Here we focus on disordered placement of these holes in a dielectric waveguide to achieve localization. Therefore we perform FDTD field simulations to calculate the Purcell factor, which can quantifies the light matter interaction. And we investigate the spectral features of the modes in the disordered structures. Thereby we find Purcell factors up to 25.
