Plasmon-mediated magneto-optical transparency

Abstract

Magnetic field control of light is among the most intriguing methods for modulation of light intensity and polarization on sub-nanosecond timescales. The implementation in nanostructured hybrid materials provides a remarkable increase of magneto-optical effects. However, so far only the enhancement of already known effects has been demonstrated in such materials. Here we postulate a novel magneto-optical phenomenon that originates solely from suitably designed nanostructured metal-dielectric material, the so-called magneto-plasmonic crystal. In this material, an incident light excites coupled plasmonic oscillations and a waveguide mode. An in-plane magnetic field allows excitation of an orthogonally polarized waveguide mode that modifies optical spectrum of the magneto-plasmonic crystal and increases its transparency. The experimentally achieved light intensity modulation reaches 24%. As the effect can potentially exceed 100%, it may have great importance for applied nanophotonics. Further, the effect allows manipulating and exciting waveguide modes by a magnetic field and light of proper polarization.

Tunable and switchable polarization rotation with non-reciprocal plasmonic thin films at designated wavelengths

“…[3][4][5][6] Such a magnetic field can also influence the intensity of light transmitted and reflected in scenarios of the transverse magneto-optical Kerr effect [7][8][9] and longitudinal magneto-photonic intensity effect. 10 Applying a magnetic field to magneto-optical materials can also change the nonlinear optical effects of the material. [11][12][13][14][15] These physical effects provide us with versatile approaches to develop magnetically tunable devices.…”
