A nanolaser with extreme dielectric confinement. [PDF]
Sci AdvThe interaction between light and matter can be enhanced by spatially concentrating the light field and extending photon dwell time. Plasmonic structures can provide strong light confinement but suffer from ohmic losses. Recent advances in dielectric nanostructures enable strong light localization without metallic losses.
