Figure 3. ST-ELED as source of polarization entangled photons.

Figure 3

(a) Co-polarized (blue) correlation and cross-polarized (red) correlation counts (G(2)(τ)) for a QD in an ST-ELED excited with electrical pulses with 185.2 MHz repetition rate, measured in the rectilinear, diagonal and circular bases. Representative density matrix Inline graphic: (b) real part and (c) imaginary part, which are reconstructed with 16 coincidence counts integrated in a 1.8-ns temporal window centred at 0 delay time.
