“…Nearly total transmission is demonstrated in a cross-polarization regime in one direction, while the transmission in the opposite direction at the same polarization of the incident wave is blocked. Possible applications include microwave and optical isolation, integrated photonic circuits, ultrafast information processing and optical interconnects [14]. To the authors' knowledge, diodelike asymmetric transmission of linearly polarized waves at normal incidence has not been observed before.…”

An asymmetric, reciprocal, diffraction-free transmission of linearly polarized waves in a new diodelike, three-layer, ultrathin, chiral structure is studied theoretically and experimentally. The exploited physical mechanism is based on the maximization of the cross-polarized transmission in one direction due to the polarization selectivity dictated by the peculiar eigenstate combination, which is efficiently controlled by the electromagnetic tunneling through the metallic subwavelength mesh sandwiched between these layers. Simulation and microwave experiment results demonstrate a nearly total intensity transmission at normal incidence in one direction and a small intensity transmission in the opposite direction.

“…Subsequently, Cakmakyapan et al reported a low-power all-optical diode in an asymmetric metallic grating heterostructure with a subwavelength slit [17]. Our group also realized a low-power all-optical diode based on tunable surface plasmon polaritons (SPPs) in a silver grating coated with nonlinear optical material [18]. However, the propagation direction of the signal light is perpendicular to the metal film [17,18].…”

A nanoscale surface plasmon all-optical diode is proposed based on a plasmonic slot waveguide having an asymmetric plasmonic grating in the center. The asymmetric configuration of the plasmonic grating and the unique dispersion relations of the plasmonic slot waveguide ensure the nonreciprocal transmission properties. High transmittance contrast ratio of 1,150 is achieved theoretically. The performance of the surface plasmon all-optical diode does not have any high power requirement. This may open a new way for the study of integrated photonic devices based on surface plasmons.

“…[13][14][15] Recently, the diodelike asymmetric transmission effect for metamaterials has attracted growing attention in the scientific community for its possible applications in polarization transformers, diodelike devices, ultrafast information processing, and optical interconnects. [14][15][16][17][18][19] Mutlu et al proposed a dual-band diodelike asymmetric transmission of linearly polarized, normally incident waves by designing a three-layer structure made of isotropic and linear materials. 11 Shi et al further demonstrated a broadband diodelike asymmetric transmission by Babinet-inverted metasurfaces constructed by an array of asymmetrical split ring apertures.…”
