“…Only within the dynamical framework one can describe the fast processes and influence of the inhomogeneous field distribution inside a gain slab, as well as correctly predict establishment of the stationary state or lasing in metal-dielectric structures [36][37][38]. For the multilayer we reveal the frames of applicability of the transfer-matrix method using comparison with the inhouse finite-difference time-domain (FDTD) method [39,40]. The FDTD approach describes the frequency-dispersive metallike material response with the time-dependent equations, while the Bloch equations are employed for dielectric having resonant gain.…”

Using the transfer-matrix approach and solving time-domain differential equations, we analyze the loss compensation mechanism in multilayer systems composed of an absorbing transparent conductive oxide and dielectric doped with an active material. We reveal also another regime with the possibility of enhanced transmission with suppressed reflection originating from the resonant properties of the multilayers. For obliquely incident and evanescent waves, such enhanced transmission under suppressed reflection turns into the reflectionless regime, which is similar to that observed in the PT -symmetric structures, but does not require PT symmetry. We infer that the reflectionless transmission is due to the full loss compensation at the resonant wavelengths of the multilayers.

“…Previously, S-shaped-like structures have been proposed for perfect transmission/reflection, [52] chirality control, [53,54] and nonlinear coupling with trapped-mode resonances. [55] Here, we innovatively expand the nanophotonics applications of S-shaped nanostructure for optimal polarization conversion and control of nonlinear signal. Due to the inherently low radiative loss in the toroidal resonance, a record-high linear crosspolarization conversion of 22.9% in the optical frequency is experimentally obtained, which is comparable to the theoretical limit.…”

The recent progress in plasmonic metasurfaces gives rise to an intense evolution of controlling light properties such as phase, amplitude, polarization, and frequency. In this work, a new paradigm is established to control the light properties centered on low‐loss toroidal multipoles with high field enhancement in contrast to most of the previous plasmonic metasurfaces that are optimized through electric and magnetic multipolar resonances. Through a proof‐of‐concept demonstration, a linear cross‐polarization conversion efficiency reaching 22.9%, remarked as the optimal value that can exist in a single‐layer plasmonic metasurface in the near‐infrared spectrum, is experimentally realized. A polarization‐insensitive toroidal response, that previously was accessible only in isotropic high‐index metasurfaces, is also observed. Furthermore, a giant anisotropic (polarization‐sensitive) generation of the second‐harmonic frequency is demonstrated with the proposed polarization‐independent toroidal metasurface that provides different levels of electric energy storage within the metasurface. These findings open a new path for keeping low‐efficiency plasmonic components on track when one engineers a metasurface based on the toroidal multipole family.

“…The trapped mode has a high Q factor because of its small radiation loss, so it can be used in sensor and modulator [11][12][13][14][15]. Researchers have focused on MMs containing a single trapped mode observed in simple one-meta-atom MMs for a long time, and in recent years, multiple trapped modes, usually excited in a complicated multi-meta-atom called metamolecule MMs, have attracted extensive attention due to their superior performance in terms of modifying resonant waveforms at multiple spectral locations simultaneously [16][17][18][19][20]. For example, two or more trapped modes are demonstrated in MMs with a double-chain meander wire array or two different lattices of metamolecules [19,20].…”

We numerically and experimentally demonstrated double Fano resonances in a simple S-shaped plasmonic metasurface in the terahertz frequency range. Apart from the electric-LC resonance and electric dipole (ED) resonance, two trapped modes are excited in two different types of asymmetric S-shaped structures in the frequency range 0.2-1.4 THz, which are mainly attributed to a magnetic dipole (MD) and an electric quadrupole (EQ). Thereafter, double Fano resonances [one Fano and one electromagnetically induced transparency (EIT) resonance] are achieved via the coupling of the two dark trapped modes and a broad bright ED at normal incidence of the metasurfaces. Furthermore, under oblique incidence, strong Fano responses can be observed; they are considerably enhanced in asymmetric structures, and even in a symmetric structure. The proposed S-shaped plasmonic metasurfaces are easy to fabricate and have potential applications in multi-wavelength optical switches, filters, and sensors.
