Cavity-enhanced light–matter interaction in Vogel-spiral devices as a platform for quantum photonics

Enhancing light–matter interactions on a chip is of paramount importance for classical and quantum photonics, sensing, energy harvesting applications. Several photonic geometries have been developed, allowing high extraction efficiencies, enhanced interactions, control over the spontaneous emission dynamics solid-state light sources. To this end, device geometry resilient to nanofabrication imperfections, providing high-quality confinement emitted properties, would be desirable. We demonstrate that aperiodic arrangements, whose inspired by natural systems where scattering elements are arranged following Fibonacci series, represent platform enhancing interaction in on-chip nanophotonic devices, us achieve efficient visible confinement. use optically active defect centers silicon nitride as internal sources image characterize, means microphotoluminescence spectroscopy, individual optical modes confined membranes with Vogel-spiral geometry. By studying statistics measured resonances, combination rigorous multiple theory, we observe lognormal distributions report quality factors values 2201 ± 443. Our findings improve understanding fundamental physical properties light-emitting show their application devices. These results set basis further development devices leverage unique Vogel spiral order chip, including angular momentum states, thus producing mode structures information processing communications.
