Hybrid metal-dielectric nanocavity for enhanced light-matter interactions

Hybrid metal-dielectric nanocavity for enhanced light-matter interactions

Despite tremendous advances in the fundamentals and applications of cavity quantum electrodynamics (CQED), investigations in this field have primarily been limited to optical cavities composed of purely dielectric materials. Here, we demonstrate a hybrid metaldielectric nanocavity design and realize it in the InAs/GaAs quantum photonics platform utilizing angled rotational metal evaporation. Ke...

Magnetic light-matter interactions in a photonic crystal nanocavity.

We study the magnetic coupling between a metal-coated near-field probe and a photonic crystal nanocavity. The resonance of the nanocavity shifts to shorter wavelengths when the ringlike apex of the probe is above an antinode of the magnetic field of the cavity. We show that this can be attributed to a magnetic light-matter interaction and is in fact a manifestation of Lenz's law at optical freq...

Title Magnetic Light-Matter Interactions in a Photonic Crystal Nanocavity

Enhanced light-matter interaction in atomically thin MoS2 coupled with 1D photonic crystal nanocavity.

Engineering the surrounding electromagnetic environment of light emitters by photonic engineering, e.g. photonic crystal cavity, can dramatically enhance its spontaneous emission rate through the Purcell effect. Here we report an enhanced spontaneous emission rate of monolayer molybdenum disulfide (MoS2) by coupling it to a 1D silicon nitride photonic crystal. A four times stronger photolumines...

Strong Light-Matter-Interactions in Nanocavities and 2D Material-Nanocavity Systems

We report on showing strong light-matter-interaction enhancements of waveguide-integrated and 2D material-based spiral nanocavities. Both exploit high Q/Vmode values outperforming diffraction-limited cavities due to high optical densities. ©2015 Optical Society of America OCIS codes: (350.4238), (250.5403), (190.4720), (230.7370) , (160.4236) , (010.1030) The deployment of ...
