Abstract

Recently we have shown that a nanofiber excited by a localized electric source can have enhanced electric and magnetic response depending of the relative orientation of the source and the fiber [1]. We have demonstrated that the dielectric nanofiber can suppress the electric response and enhance the magnetic response of the coupled system when excited with an electric dipole oriented along the circumference of the fiber. This result introduces a new platform for achieving enhanced magnetic response, which is the fundamental building block for metamaterial devices. Here we investigate experimentally the scattering of THz radiation from a sub-wavelength fiber excited by a localized source. We observe resonance peaks in the scattered light and attribute them to combined excitation of several lower order Whispering Gallery Modes (WGMs) of the fiber. To the best of our knowledge, this is the first demonstration of sub-wavelength fiber resonances at THz frequencies due to a localized source.
