“…This has led to the combination of noble and ferromagnetic metals as suitable magnetoplasmonic systems. 15,16,[28][29][30][31] The possibility of realizing magnetic field driven SPP modulators has been recently demonstrated using this kind of system. 15 Moreover, the modulation can be increased with the addition of a thin dielectric layer on top of the metallic multilayer, 16 or by optimizing the quality of the interfaces.…”

Spectral dependence of the magnetic modulation of surface plasmon polaritons in noble/ferromagnetic/noble metal films

et al. 2012

The magnetic field is an interesting candidate for the development of active plasmonic devices as it is able to modify the surface plasmon polariton (SPP) wave vector. Both real and imaginary parts of the SPP wave vector are affected. Here, we have experimentally determined the contribution of both modulations in the spectral range λ 0 = 500-1000 nm for magnetoplasmonic systems consisting of noble/ferromagnetic/noble multilayered metal films. We have seen that the real part usually exceeds the imaginary one, but in the longer wavelength range the contribution of the imaginary part cannot be neglected. We have analyzed the spectral dependency of the modulation, and we conclude that it is dominated by the evolution of the SPP properties with wavelength and not the magneto-optical parameter. A figure of merit including modulation and propagation distance is also studied for the three ferromagnetic metals, Fe, Co, and Ni.

“…So far, there are two main ways to solve this problem. The first one is using composite materials, including metals and ferromagnetic materials, such as Ni and Co [55][56][57][58][59][60][61][62]. Using this method, due to the strong magnetization of the ferromagnetic materials, the applied magnetic field can be as weak as several ∼mT.…”

Due to their promising properties, surface magneto plasmons have attracted great interests in the field of plasmonics recently. Apart from flexible modulation of the plasmonic properties by an external magnetic field, surface magneto plasmons also promise nonreciprocal effect and multi-bands of propagation, which can be applied into the design of integrated plasmonic devices for biosensing and telecommunication applications. In the visible frequencies, because it demands extremely strong magnetic fields for the manipulation of metallic plasmonic materials, nano-devices consisting of metals and magnetic materials based on surface magneto plasmon are difficult to be realized due to the challenges in device fabrication and high losses. In the infrared frequencies, highly-doped semiconductors can replace metals, owning to the lower incident wave frequencies and lower plasma frequencies. The required magnetic field is also low, which makes the tunable devices based on surface magneto plasmons more practically to be realized. Furthermore, a promising 2D material-graphene shows great potential in infrared magnetic plasmonics. In this paper, we review the magneto plasmonics in the infrared frequencies with a focus on device designs and applications. We investigate surface magneto plasmons propagating in different structures, including plane surface structures and slot waveguides. Based on the fundamental investigation and theoretical studies, we illustrate various magneto plasmonic micro/ nano devices in the infrared, such as tunable waveguides, filters, and beam-splitters. Novel plasmonic devices such as one-way waveguides and broad-band waveguides are also introduced.

“…[10][11][12][13] For example, the in-plane modification of surface plasmon polaritons (SPPs) behavior on smooth magnetoplasmonics films [14][15][16][17] and nanostructures 18-20 by external magnetic field has been carried out both theoretically and experimentally. One-way waveguiding and one-way extraordinary optical transmission were proposed by integrating magneto-optic (MO) materials with photonic crystal 21 and spoof surface plasmons, 22 respectively.…”

“…Electric resistance of our structure is about 10 X. Transverse magneto-optical Kerr effect (TMOKE) of MO material can be greatly enhanced by magnetoplasmonics. Different kinds of magnetoplasmonic multilayer structure have been studied by Ferreiro-Vila et al 15,16 The TMOKE of our sample was investigated by using p-polarized He-Ne laser radiation (k ¼ 632.8 nm) and lock-in technique, as shown in Fig. 1.…”

The ability to actively control light has long been a major scientific and technological goal. We proposed a scheme that allows for active control of light by utilizing the nonreciprocal magnetoplasmonic effect. As a proof of concept, we applied current signal through an ultrathin metallic film in a magneto-plasmonic multilayer and found that dynamic photonic nonreciprocity appears in magnetic-optical material layer due to the magnetic field being induced from current signal and modulates surface plasmon polaritons trapped in the metal surface and the light reflected. The proposed concept provides a possible way for the active control of light and could find potential applications such as ultrafast optoelectronic signal processing for plasmonic nanocircuit technology and ultrafast/large-aperture free-space electro-optic modulation platform for wireless laser communication technology.
