Fig. 4: Magnetic field dependence of long-lived spin-dependent photon echo.
From: Extending the time of coherent optical response in ensemble of singly-charged InGaAs quantum dots
Magnetic field dependence of the main parameters (decay rate, phase and amplitude) of long-lived spin-dependent photon echo signal evaluated from the three-pulse transients PHVVH(τ23) measured at different B. a decay rate \(\hslash /{T}_{{{{{{{{\rm{2,e}}}}}}}}}^{* }\); b phase ϕe; c amplitude re. Blue points correspond to the data resulting from the fit using the last term on the right-hand side in Eq. (4). Error bars represent confidence interval evaluated from the fit. In a and c the error is given by the size of the symbol. Red dashed line in a is the fit by linear function from Eq. (5) with T2,e = 4.3 ns and Δge = 4 × 10−3. Red solid line in b and c—magnetic field dependences of ϕe and re given by Supplementary Eqs. (56) and (57).
