Ultrahigh-Q metallic nanocavity resonances with externally-amplified intracavity feedback
We propose a mechanism of ultrahigh-Q metallic nanocavity resonances that involves an efficient loss-compensation scheme favorable for room-temperature operation. We theoretically show that surface plasmon-polaritons excited on the entrance and exit interfaces of a metallic nanocavity array efficiently transfer external optical gain to the cavity modes by inducing resonantly-amplified intracavi...
متن کاملHighly enhanced fluorescence of fluorophores inside a metallic nanocavity.
Here we report the observation of significantly enhanced fluorescence from molecules placed inside a silver nanocavity, as compared to those without the silver coating.
متن کاملHigh-Q photonic crystal slab nanocavity with an asymmetric nanohole in the center for QED
We present a new approach which allows one to insert a silica nanosphere with a single quantum dot into a highQ photonic crystal slab nanocavity with an asymmetric nanohole in the center. The high Q cavity is optimized by adjusting air holes around the L3-type cavity based on three-dimensional finite-difference time-domain simulation. High Q value of 48 700 in this asymmetric cavity is achieved...
متن کاملHigh Q whispering gallery modes in GaAs/AlAs pillar microcavities.
We report the observation of whispering gallery modes (WGM) in high quality GaAs/AlAs pillar microcavities defined by electron-beam lithography and electron cyclotron resonance reactive ion etching. Photoluminescence experiments, conducted using InAs quantum dots as an internal probe, reveal a remarkably simple WGM spectrum, consisting of a single series of TE modes. For diameters ranging from ...
