Electric Spaser in the Extreme Quantum Limit    [PDF]

Dabing Li, Mark I. Stockman
We consider theoretically the spaser excited electrically via a nanowire with ballistic conductance. We show that in the extreme quantum regime, i.e., for a single conductance-quantum nanowire, the spaser with the core made of common plasmonic metals, silver and gold, is fundamentally possible. For ballistic nanowires with multiple-quanta or non-quantized conductance, the performance of the spaser is enhanced in comparison with the extreme quantum limit.
