Single-Photon Emission by the Plasmon-Induced Transparency Effect in Coupled Plasmonic Resonators

The plasmon-induced transparency (PIT) effect with unique spectrum transmission characteristics is a significant property of plasmonic structures. A resonant nanocavity nanoscale dimensions around single-photon emitter dramatically enhances the emission rate emitter. Thus, we propose detuned nanocavities to manipulate inside, which either cell consists rectangular resonator surrounded by U-like resonator. An InGaAs quantum dot in GaAs nanowire placed center was employed as finite-difference time domain simulation revealed that distribution electromagnetic field can be affected changing coupling intensity between bright and dark states PIT. Consequently, enhanced more than 2000 times due Purcell induced PIT cavity. With achievement an ultrafast rate, proposed could have diverse applications information communications.
