Fig. 4. Active control of tip-induced single QD strong coupling.
TEPL spectra as the lateral (A) and vertical (B) tip-QD distances are varied from 30 to 0 nm and from 0 to 4 nm, respectively. (C and D) Coupling strength g and Rabi frequency Ω derived from model fit of the distance-dependent TEPL spectra from (A) and (B).
