We
propose and demonstrate theoretically bright coherent radiation
from a plasmonic nanoresonator powered by a single three-level quantum
emitter. By introducing a dual-pump scheme in a Raman configuration
for the three-level system, we overcome the fast decay of nanoplasmons
and achieve macroscopic accumulation of nanoplasmons on the plasmonic
nanoresonator for stimulated emission. We utilize the optical antenna
effect for efficient radiation of the nanoplasmons and predict photon
emission rates of 100 THz with up to 10 ps duration pulses and GHz
repetition rates with the consideration of possible heating issue.
We show that the ultrafast nature of the nanoscopic coherent source
allows for operation with solid-state emitters at room temperature
in the presence of fast dephasing. We provide physical interpretations
of the results and discuss their realization and implications for
ultracompact integration of optoelectronics.
