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…

Mid-Infrared Single-Photon Detection via Enhanced Cross-Phase Modulation in Topology-Optimized Epsilon-Near-Zero Dual-Wavelength Nanocavities

Luca Dal Negro, Riccardo Franchi, Marco Ornigotti

We use the Green's tensor quantization theory for open resonant nanostructures with absorption losses to study cross-phase modulation (XPM) at the single-photon level in nanoscale…

Structural and physical properties of gyromorphs and disordered stealthy hyperuniform media

Murray Skolnick, Riccardo Franchi, Luca Dal Negro +2

Disordered stealthy hyperuniform materials combine liquid-like statistical isotropy with crystal-like homogeneity, suppressed density fluctuations at large length scales, bounded h…

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…

High-throughput speckle spectrometers based on multifractal scattering media

Bhupesh Kumar, Yilin Zhu, Luca Dal Negro +1

We present compact integrated speckle spectrometers based on monofractal and multifractal scattering media in a silicon-on-insulator platform. Through both numerical and experiment…
