Magnetized spiral chains of plasmonic ellipsoids for one-way optical waveguides.
When a linear chain of plasmonic nanoparticles is subject to longitudinal magnetic field, it exhibits optical Faraday rotation. If the magnetized nanoparticles are plasmonic ellipsoids arranged as a spiral chain, the interplay between the Faraday rotation and the geometrical spiral rotation (structural chirality) can strongly enhance nonreciprocity. This interplay forms a waveguide that permits...
متن کاملPolarisation rotation in resonant emission of semiconductor microcavities
We present the semi-classical theory of the non-linear propagation of polarized light in semiconductor microcavities. This formalism explains the mysterious rotation of the polarization plane of light emitted by a microcavity in the regime of stimulated scattering observed recently. The model describes the stimulated four-wave mixing in microcavities. We show that the exciton spin-splitting ind...
متن کاملDirect Estimation of Faraday Rotation and Other System Distortion Parameters from Polarimetric Sar Data
One of the major impacts of the Earth’s ionosphere on spaceborne radar signals is the rotation of the polarization vector, also called the Faraday rotation (FR) effect. The FR effect increases with decreasing frequency. It is reported [1] that estimated maximum FR values under peak ionospheric total electron content (TEC) conditions range from 2.5 degrees (C-band) to more than 320 degrees (P-ba...
متن کاملPlasmon enhanced direct and inverse Faraday effects in non-magnetic nanocomposites
While applications of plasmonics are rapidly growing, magneto-optical effects in nanocomposites are poorly understood. We therefore devote this paper to the theoretical analysis of magneto-optical effects in nanocomposites. Based on the Drude model, we derived the constitutive equation where the dielectric and coupling functions describe the interactions of metal nanoparticles with magnetic fie...
متن کاملGyrotropic-nihility in Ferrite-semiconduc- Tor Composite in Faraday Geometry
The reflection, transmission spectra and the polarization transformation of linearly polarized waves in the ferrite-semiconductor multilayer structure are considered. In the long-wavelength limit, the effective medium theory is applied to describe the studied structure as a uniaxial anisotropic homogeneous medium defined by the effective permittivity and effective permeability tensors. The inve...
