Quantum Theory of Third-harmonic Generation in Epsilon-Near-Zero Materials
Sonia Alipour, Riccardo Franchi, Tornike Shubitidze +3
We present a theoretical framework, based on the Green's tensor quantization method, to describe third-harmonic generation in epsilon-near-zero (ENZ) materials and derive analytica…
Enhancement of the Third Harmonic Generation Efficiency of ITO nanolayers coupled to Tamm Plasmon Polaritons
Tornike Shubitidze, Smridhi Chawla, Luca Dal Negro
We study the enhancement of third harmonic generation in indium tin oxide nanolayers coupled to Tamm plasmon polaritons (TPPs). The TPPs are excited at the interface between a thin…
Localization landscape of optical waves in multifractal photonic membranes
Tornike Shubitidze, Yilin Zhu, Hari Sundar +1
In this paper, we investigate the localization properties of optical waves in disordered systems with multifractal scattering potentials. In particular, we apply the localization l…
Enhanced Nonlinearity of Epsilon-Near-Zero Indium Tin Oxide Nanolayers with Tamm Plasmon-Polariton States
Tornike Shubitidze, Wesley A. Britton, Luca Dal Negro
Recently, materials with vanishingly small permittivity, known as epsilon-near-zero (ENZ) media, emerged as promising candidates to achieve nonlinear optical effects of unprecedent…
Field theory description of the non-perturbative optical nonlinearity of epsilon-near-zero media
Yaraslau Tamashevich, Tornike Shubitidze, Luca Dal Negro +1
In this paper we introduce a fully non-perturbative approach for the description of the optical nonlinearity of epsilon-near-zero (ENZ) media. In particular, based on the rigorous…
Inverse design of functional photonic patches by adjoint optimization coupled to the generalized Mie theory
Yilin Zhu, Yuyao Chen, Sean Gorsky +2
We propose a rigorous approach for the inverse design of functional photonic structures by coupling the adjoint optimization method and the two-dimensional generalized Mie theory (…
Enhanced wave localization in multifractal scattering media
Yuyao Chen, Fabrizio Sgrignuoli, Yilin Zhu +2
In this paper we study the structural, scattering, and wave localization properties of multifractal arrays of electric point dipoles generated from multiplicative random fields wit…
