Correlation and locking maps of two coupled micropillar lasers. Measured a and simulated c weak-mode intensity cross-correlation \(g_{{\mathrm{w}}_1{\mathrm{w}}_2}^{(2)}(\tau = \tau _2 - \tau _1)\) (color-coded) in face-to-face configuration as function of the time delay τ for different detunings νw (IP1 = 28.0 μA and IP2 = 25.6 μA). b, d Corresponding log-intensity Fabry–Perot interferometer (FPI) spectra (color-coded) of the laser output in dependence of the detuning νw. IP1 = 28.6 μA, IP2 = 27.0 μA in the experiments, IP1 = 27.1 μA, IP2 = 24.4 μA in the simulations
