“…Therefore, by exciting surface plasmon polaritons (SPPs), the ultra-loss plasmonic EIT systems can be achieved [193][194][195], where the gain compensated structures/materials play the key roles. In addition, active controls of EM characteristics can be realized in ultraloss PIT metamaterial systems by applying external magnetic fields [196][197][198][199] or introducing nonlinear components [196]. For example, Jalali-Mola et al proposed a general nonlinear plasmonic waveguide configuration, where a tunable nonlinear layer is situated on top of a plasmonic system [196].…”

Electromagnetically induced transparency (EIT) stems from a quantum system, where an opaque atomic medium appears the narrow transparent state within a wide absorption area. This phenomenon can be achieved by quantum interference of pumping light and detecting light at different energy levels of transitions. In the generation process of EIT effect, in addition to transparent state, the atomic medium is usually accompanied with a strong dispersion effect, which will bright about a significant reduction of light velocity, thus realizing many important applications, such as slow light propagations. Although the EIT effect has many important applications, its application scenarios are greatly limited due to the fact that EIT realization usually requires specific and complicated conditions, such as refrigeration temperature, high intensity laser, etc. Recently, the analogue of EIT effect in metamaterial has attracted increasing attentions due to its advantages such as controllable room temperature and large operating bandwidth. Metamaterial analogue of EIT effect has become a new research focus. In this article, we review current research progresses on EIT metamaterials. Firstly, we describe the theoretical models for analyzing EIT metamaterials, including the mechanical oscillator model and the equivalent circuit model. Then, we describe the simulations, designs and experiments of passive EIT metamaterials with fixed structures and active EIT metamaterials with tunable elements. Furthermore, the applications of EIT metamaterials in the areas of slow lights, sensings, absorptions and other fields are also reviewed. Finally, the possible directions and key issues of future EIT metamaterial researches are prospected.

Bloch oscillation is a phenomenon from solid state physics, describing a wave packet in periodic potential undergoing periodic oscillations in space, returning to the initial position after one oscillation cycle, under the action of a weak constant force. This wave phenomenon pertains to many physical systems including acoustic or optical resonators, and optical waveguides. Herein, we demonstrate discrete diffraction and Bloch oscillations, in a non-Hermitian electric circuit chain with anti-parity-time (APT) symmetry. The electric circuit chain consists of an LC circuit with operational amplifiers. We theoretically investigate the time-domain dynamics in different symmetry phases of the system. The time evolution of the envelope of voltage is in excellent agreement with coupled mode theory numerical calculations.

“…At last, introducing external potential fields to change the electromagnetic environment in the system can also be used to modulate properties of SPPs [31][32][33][34][35][36][37][38][39]. e.g., by using a beam of control light with a specific polarization state to shine on the surface of aluminium, then the refractive index of aluminum will change due to its absorption of control light, thus, the SPPs can be manipulated by the incident light field [31]; the phase information and trajectory of SPPs can be modulated by introducing an external gradient magnetic field [32][33][34]. Besides, there are some other kinds of external potential fields can be used to realize the modulation of SPPs, such as electric field [35][36][37] and thermal field [38,39].…”

We propose a scheme to study the nonlinear propagation properties of nonlinear surface plasmon polaritons (SPPs) in a three level Λ type electromagnetically induced transparency (EIT) system with modulation of a rectangular barrier. Based on the multi scale method, the nonlinear Schrödinger equation (NLSE) describing nonlinear propagation of SPPs is derived, and the rectangular barrier affecting propagation of nonlinear SPPs is provided by an off-resonance Stark field. For the single nonlinear SPPs incident case, by adjusting the height and half width of the barrier, we can realize transmission, trapping and reflection of the nonlinear SPPs. For two nonlinear SPPs symmetrical incident case, we find that a periodic intensity distribution in transverse direction mode can be excited in the rectangular barrier, and we study the relationship between propagation properties of such excited modes in the barrier with nonlinearity, half width of the barrier and phase difference of the initial nonlinear SPPs. In addition, we design an optical switch of nonlinear SPPs based on the above results. The results obtained here not only provide a theoretical basis for the study of the interaction between nonlinear SPPs and external potentials, but also have broad application prospects in the field of optical information at micro/nano scale.
