Multiple scattering of light in optical fibers with a nanoscopic core — •Harald R. Haakh, Sanli Faez, and Vahid Sandoghdar — Max Planck Institut für die Physik des Lichts, Erlangen

Multiple scattering of light in reduced dimensions and particularly in waveguiding structures such as photonic crystal waveguides, has garnered interest lately both in experiment and theory as it may give rise to Anderson localized states and random cavity formation. We investigate the coupling of quantum scatterers to the fundamental mode of an optical fiber with a nanoscopic (or subwavelength) core as a versatile platform for the study of light transport through a one-dimensional multiply scattering medium. A rigorous theoretical treatment based on dyadic Green tensors allows for a careful analysis of the role of scattering into non-guided modes and its influence on the transport properties. Our results indicate the persistence of localized states under limited emitter-fiber coupling and may also be transferred to other waveguiding structures.
