Optical amplification using raman transitions between spin-singlet and spin-triplet states of a pair of coupled in-GaAs quantum dots

We report the observation of steady-state optical amplification in Raman transitions between the lowest-energy spin states of a single quantum-dot molecule. Absorption and resonance fluorescence experiments demonstrate that the entangled two-electron singlet and triplet states have electric-dipole c...
