“…In order to understand the ability of the proposed structures to enhance some nonlinear effects, it is required to estimate the intensity of the inner field which is localized within the system. The special geometry of the metamaterial with symmetrical DR allows us to obtain an analytical expression for this demand [12,13]. So, at the trapped-mode resonance, the electromagnetic energy is confined to a very small region between the rings.…”

“…In the present days, the theory of nonlinear metamaterials is actively developing [10][11][12][13] in the fields of controlling light with light [14], and parametric conversion of optical harmonics [15]. Here a particular interest is to study the peculiarities of intense light interaction with planar structures which sustain the trappedmode resonant regime, and contain nonlinear components.…”

We present a theory which explains how to achieve an enhancement of nonlinear effects in a thin layer of nonlinear medium by involving a planar periodic structure specially designed to bear a trapped-mode resonant regime. In particular, the possibility of a nonlinear thin metamaterial to produce the bistable response at a relatively low input intensity due to a large quality factor of the trapped-mode resonance is shown. Also a simple design of an all-dielectric lowloss silicon-based planar metamaterial which can provide an extremely sharp resonant reflection and transmission is proposed. The designed metamaterial is envisioned for aggregating with a pumped active medium to achieve an enhancement of quantum dots luminescence and to produce an all-dielectric analog of a 'lasing spaser'.Keywords: metamaterial, trapped-mode, nonlinear optics, bistability, luminescence IntroductionOne of the current trends in the theory of metamaterials is the development of two-dimensional planar periodic systems (metasurfaces, metamaterials) constructed in the form of arrays of resonant metallic or dielectric particles, which are arranged periodically on a thin (compared with the wavelength) dielectric layer. It is known that such planar metamaterials can create an environment whose electromagnetic characteristics are similar to those achieved in the traditional cavity resonators, but, unlike the latter, planar structures can have a much smaller size.

“…The features of nonlinear trapped-mode resonances were previously studied theoretically in planar metamaterials composed of asymmetrical split-rings [11] and two concentric rings [12][13][14]. In both configurations the substrate which carries the metallic pattern is considered as a nonlinear dielectric.…”

Nonlinear interaction of two trapped-mode resonances in a bilayer fish-scale metamaterial

We report on a bistable light transmission through a bilayer "fish-scale" (meander-line) metamaterial. It is demonstrated that an all-optical switching may be achieved nearly the frequency of the high-quality-factor Fano-shaped trapped-mode resonance excitation. The nonlinear interaction of two closely spaced trapped-mode resonances in the bilayer structure composed with a Kerr-type nonlinear dielectric slab is analyzed in both frequency and time domains. It is demonstrated that these two resonances react differently on the applied intense light which leads to destination of a multistable transmission.

“…Earlier analysis of the electromagnetic characteristics of such planar metamaterials was provided both in microwave and optical bands. It was found out that this high-Q resonant regime of the trapped mode excitation in such planar structures is promising for enhancement of several effects which are associated with using active and nonlinear materials [3][4][5].Particularly it was revealed [6-8] that the effect of the strong resonant absorption appears at frequencies of the trapped mode excitation in the fish-scale metamaterials made of the grating in the form of meander-line or wavy-line metal strips which are placed on a lossy dielectric layer backed with a metal mirror. It is significant that the absorption in such metamaterials is much higher than that one caused by losses in the detached dielectric layer without the grating.…”

The possibility of achievement of the reflected field amplification by the metamaterial made of microstrip grating placed on the layer of an optically gain dielectric is shown. The comparison of obtained results with ones known for the metamaterial with a lossy substrate is curried out.The development of quantum electronics and laser optics has led to the need of improvement and, in some cases, to revision of the principles of reflection and transmission of light at the conditions when the reflecting medium is optically gain or nonlinear. It is revealed that in this situation some well-studied optical effects can appear with some new features. In particular, when light is reflected from the boundary of an optically gain (active) medium, the reflection coefficient may be more than unit under some conditions, i.e. it becomes possible to amplify the reflected electromagnetic radiation.Among known planar metamaterial configurations, one stands out because of its capability to bear socalled high-Q trapped-mode resonant regime [1, 2]. Its excitation in planar structures is associated with a slight spatial asymmetry of inclusions within the periodic cell of the metamaterial. Earlier analysis of the electromagnetic characteristics of such planar metamaterials was provided both in microwave and optical bands. It was found out that this high-Q resonant regime of the trapped mode excitation in such planar structures is promising for enhancement of several effects which are associated with using active and nonlinear materials [3][4][5].Particularly it was revealed [6-8] that the effect of the strong resonant absorption appears at frequencies of the trapped mode excitation in the fish-scale metamaterials made of the grating in the form of meander-line or wavy-line metal strips which are placed on a lossy dielectric layer backed with a metal mirror. It is significant that the absorption in such metamaterials is much higher than that one caused by losses in the detached dielectric layer without the grating. This regime exists due to the current resonance induced by the strips which leads to the substantial field localization inside the system. The latter one results in the significant increasing of the absorption inside the dielectric substrate of the metamaterial. However, the resonant frequency and level of absorption can be controlled by choosing the form of strips and permittivity of the substrate. The goal of the present report is to show the possibility obtaining significant amplification of the reflected field in the case when the grating of such a planar metamaterial is placed on an optically gain substrate.The studied structure (Fig.
