“…In this work, we study the band structure of a perfect comb-like waveguides system and the transmission rate for an asymmetric comb-like structure. This structure is composed by the periodicity of segments (RHM)) of length d 1 grafted on each site by a finite number of asymmetric resonators (ENG) [34,35] of lengths d 2 and d 3 . Firstly, we have studied a simple case when we consider that two asymmetric resonators located between two semi-infinite segments.…”

In this paper, we give an analytical demonstration of electromagnetic induced transparency (EIT) resonance by a simple photonic device consisting of two grafted resonators (metamaterials of type Epsilon Negative Gauchy (ENG)) of lengths d2 and d3. Then, we study theoretically the transmission spectrum and the dispersion relation of periodic photonic comb-like waveguides system built of periodic segments of length d1 (of right-handed material). The electrical permittivity, ε, of the two asymmetric resonators with lengths d2 and d3, depends on the frequency of the incident waves (ENG material). The presence of geometrical (ENG resonators) defects inside the perfect structure creates the defect modes inside the band gaps. Consequently, we demonstrate the existence of two filtered frequencies. This structure can be used as a new photonic filter in the microwave range with an important quality factor and a high transmission rate.

“…However, these phasematching techniques were implemented in nonlinear metamaterials for radio frequency or microwave regions. To deal with nonlinear frequency conversions in optical region, hyperbolic metamaterials (HMM) were proposed to study theoretically and experimentally [10][11][12][13]. The HMMs were developed by metal-dielectric multilayer or metal nanowires arrangement in dielectric host [14].…”

“…The engineered dispersion of the HMMs was used to improve the nonlinear frequency conversions i.e., second-harmonic generation (SHG) [10][11], third-harmonic generation (THG) [12][13], and difference-frequency generation (DFG) [15]. Especially, the ENZ at interacting wavelength, which is raised by optimally designing of HMM structures.…”

Hyperbolic metamaterials have been widely used for nonlinear optical applications. Their unique functionality for nonlinear optics enhancement due to the hyperbolic dispersion is induced by a strong shape anisotropy. In this work, we numerically investigated the second-harmonic generation (SHG) in two-dimensional periodic arrays of aluminium gallium arsenide (AlGaAs) nanowires embedded in ordered porous aluminum oxide (Al2O3) or the nanowire hyperbolic metamaterial (NHMM). Under local effective medium approximation, the homogenization of the NHMM was achieved due to deep sub-wavelength size of each nanowire radius. Then this medium was classified as an effective uniaxial medium with anisotropic electric permittivity. The NHMM provided the spectral position of second-harmonic (SH) wavelength, which is determined at the epsilon-near-zero (ENZ) by the optimal design of NHMM structural parameters such as AlGaAs radius or fill fraction. Consequently, a gigantic increment of SHG conversion efficiency was achieved because of dramatic phase-matching at ENZ point. This mechanism is attributed to electric field enhancement of SHG inside the metamaterial. According to numerical results, the NHMM can be applied as nonlinear frequency converters in integrated nanophotonic systems.
