dc.description.abstractEnhancement of spontaneous emission has a large potential for the development of nanophotonics based applications. Due to the weak interaction of matter with the magnetic component of light, most of the effort has been directed toward the development of the nanophotonic devices for the enhancement of the electric dipole emission. However, in recent years the enhancement of magnetic dipole emission has attracted the focus of the researchers, owing to the utilization of the dielectric nanophotonic structures which have a great potential to facilitate various exciting applications such as nanolasers and single-photon sources. Despite the high interest on the magnetic dipole emission enhancement, most of the research has been focused on the visible spectrum and few studies have been reported up to present for the near infrared. In this context, a germanium hollow nanodisk resonator is presented and numerically investigated for magnetic dipole decay rate enhancement in the near-infrared spectrum. The obtained enhancement factor is much more than the previous results in the literature which are obtained via utilization of the dielectric nanostructures. The origin of electromagnetic behavior of the proposed resonator is revealed via near-electromagnetic-field enhancement maps and the multipolar decomposition of the electromagnetic scattering modes. Additionally, dependence of the enhancement factor on the geometrical parameters of the germanium hollow nanodisk resonator is studied via parameter sweep simulations. The results of this study may provide a novel strategy for the engineering of chip-scale nanophotonic applications.en_US
