Mutually coupled strong modes of the two micropillar lasers for different coupling strengths. a Detuning scans of the strong modes with high (panels a and b) and low (panels c and d) coupling strengths K. T is the transmittance of the attenuator in the coupling path. e Dependence of the locking range on the square root of the attenuator transmission (lower axis) and the coupling strength K used in numerical simulations (upper axis). The horizontal axes are scaled such that experimental and simulated data both lie on a common linear function
