Exciton Rabi oscillation in single-quantum dot: temporal measurement of oscillation and corresponding energy level splitting

摘要

A spectroscopic method, which enables characterization of a single isolated quantum dot and a quantum wave function interferometry is applied to exciton discrete excited state in InGaAs quantum dot. Long coherence of zero-dimensional excitonic states made possible the observe coherent population flopping in a 0D excitonic two-level system in a time-domain interferometric measurement and corresponding energy splitting is also manifested in an energy-domain measurement.
