We show that aperiodic photonic devices in silicon nitride and gallium arsenide allow high quality light confinement at visible wavelengths (Q factors up to 2200) and cavity quantum electrodynamic experiments with InAs quantum dots, respectively.

Aperiodic bandgap structures for enhanced quantum two-photon sources

Autor: Sean Gorsky, Luca Dal Negro, Yuyao Chen, Fabrizio Sgrignuoli

In this paper we propose a novel approach to enhance the efficiency of the two-photon spontaneous emission process that is driven by the multifractal optical mode density of photonic structures based on the aperiodic distributions of Eisenstein and G

Many natural patterns and shapes, such as meandering coastlines, clouds, or turbulent flows, exhibit a characteristic complexity that is mathematically described by fractal geometry. Here, we extend the reach of fractal concepts in photonics by exper

By leveraging the concept of isotropic stealthy hyperuniform arrays (ISHAs), in this paper, we design and experimentally demonstrate novel scattering arrays of dielectric nanoparticles, here referred to as optimized isotropic scattering arrays (OISAs

Increasing light extraction efficiency and narrowing the angular spread of light emitted from optically thick light emitting diodes (LEDs) are desirable but difficult goals to achieve. In this paper, we design, optimize, and fabricate Vogel spiral ar
