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.

“…In this paper we are interested in exploring nanostructured twodimensional metallic surfaces which may provide a platform for a realistic optical analog of one-way electronic devices such as diodes and transistors. The majority of the devices supporting unidirectional propagation of surface plasmon polaritons are based on nonlinear optics and magneto-optical(MO) effects [2]- [6]. For example, a waveguide has been designed in the form of a gap between a semi-infinite dielectric photonic crystal and a semi-infinite metal to which a static magnetic field is applied, in which electromagnetic waves can propagate in only one direction [5].…”

“…For example, a waveguide has been designed in the form of a gap between a semi-infinite dielectric photonic crystal and a semi-infinite metal to which a static magnetic field is applied, in which electromagnetic waves can propagate in only one direction [5]. It was subsequently shown [6] that if the photonic crystal in this waveguide structure is fabricated from a transparent dielectric magneto-optic material, to which the magnetic field is applied, the window of the frequencies within which the waveguide displays oneway propagation can be achieved at much lower magnetic field strengths than are required for this purpose in the structure proposed in Ref. 5.…”

We describe a surface structure consisting of a metal-air interface where the metallic part consists of two metallic segments with a periodic modulation of the interface between them. Such a structure possesses a different transmissivity for a surface plasmon polariton incident on it from one side of it than it has for a surface plasmon polariton incident on it from the opposite side. This asymmetric transmission of a surface plasmon polariton is based on the suppression of the zero-order Bragg beam which, for a certain value of the modulation depth, is not transmitted through the structure, while the diffraction efficiencies of the +1 and -1 Bragg beams can be modified by varying the period of grating and/or the angle of incidence. For a certain range of the incidence angle one can observe asymmetry in transmittance for the -1 mode while the +1 mode is completely suppressed. By varying the material and geometrical parameters of the diffractive structure one can control the contrast transmission that characterizes the degree of the asymmetry. This property of the structure is demonstrated by the results of computer simulation calculations.

“…For photonics to become a realistic alternative to electronics, compact integrated optical analogs of one-way electronic devices such as diodes and transistors, are needed. The effect of unidirectional propagation can generally occur in both reciprocal and nonreciprocal structures [1][2][3][4][5][6][7][8] . In several papers published recently the authors claimed nonreciprocity on the basis of the on the basis of various effects observed in the behavior electromagnetic propagation in linear, time-independent structures consisting of materials described by symmetric (i.e.…”

“…It may also occur due solely due to the geometry of the structure [10][11][12] . Most of the nonreciprocal devices and one-way devices are based on nonlinear optics and magneto-optical (MO) effects [1][2][3][4][5][6][7][8] . Except for the isolators based on material nonlinearity [4][5] , and the nonreciprocal frequency doubler of EM waves 6 that operates at the second harmonic frequency, the majority of other devives operate at the frequency of the fundamental signal.…”

We describe a surface structure that possesses a different transmissivity for a surface plasmon polariton incident on it from one side of it than it has for a surface plasmon polariton incident on it from the opposite side. This asymmetric transmission of a surface plasmon polariton does not require either electrical nonlinearity or the presence of a magnetic field but is a consequence solely of the geometry of the structure. We have demonstrated that a system consisting of a square array of scatterers deposited on a metal surface in a triangular mesh to which a diffractive structure is added to the left side of it reveals asymmetric transmission when the frequency of the incident SPP is in the bandgap of the plasmonic crystal. The mechanism for this property is related to the higher Bragg modes that are excited due to the diffractive structure, while the 0-order beam, due to the existence of the band gap, is not transmitted through the structure. By varying the material and geometrical parameters of the diffractive structure one can control the contrast transmission that characterizes the degree of the asymmetry.
