Ultracompact high-contrast magneto-optical disk resonator side-coupled to a plasmonic waveguide and switchable by an external magnetic field
Ji-Song Pae, Song-Jin Im, Kum-Song Ho +3
Here we propose and study a novel type of plasmonic resonators based on a metal-insulator-metal waveguide and a side-coupled magneto-optical disk controlled by an external magnetic…
Switchable plasmonic routers controlled by external magnetic fields by using magneto-plasmonic waveguides
Kum-Song Ho, Song-Jin Im, Ji-Song Pae +3
We analytically and numerically investigate magneto-plasmons in metal films surrounded by a ferromagnetic dielectric. In such waveguide using a metal film with a thickness exceedin…
Third-order nonlinearity by the inverse Faraday effect in planar magnetoplasmonic structures
Song-Jin Im, Chol-Song Ri, Kum-Song Ho +1
We predict a new type of ultrafast third-order nonlinearity of surface plasmon polaritons (SPP) in planar magneto-plasmonic structures caused by the inverse Faraday effect (IFE). P…
Magnetically-tunable cutoff in asymmetric thin metal film plasmonic waveguide
Song-Jin Im, Chol-Song Ri, Ji-Song Pae +2
We theoretically investigated the magnetically-tunable cutoff of long-range surface plasmon polariton along thin metal film surrounded by a magneto-optic material on one side and b…
Mechanism of the Fano resonance in a planar metamaterials: Analysis from the coupled two-oscillator model
Song-Kum Song, Song-Jin Im
Mechanism of the Fano resonances in planar metamaterials demonstrate based on the coupled two-oscillator model. We have described the optical spectrums like reflectance and transmi…
Suppression of DC term in Fresnel digital holography by sequence subtraction of holograms
Jong-Chol Kang, Chol-Su Kim, Song-Jin Im
An experimental method for suppression of DC term in the reconstructed images from Fresnel digital holograms is presented. In this method, two holograms for the same object are cap…
