Exceptional points in two dissimilar coupled diode lasers

We show the abundance of exceptional points in the generic asymmetric configuration of two coupled diode lasers, under nonzero optical detuning and differential pumping. We pinpoint the location of these points with respect to the stability domains and the Hopf bifurcation points of phase-locked modes, in the solution space as well as in the space of experimentally controlled parameters.
