We conduct a theoretical study of the nonlinear optical response of atwo-dimensional semi-conductor quantum dot supercrystal subjected to aquasi-resonant continuous wave excitation. Aconstituent quantum dot is odeledas a three-level ladder-like system (comprising the ground, theone-exciton, andthe bi-exction states). To study the stationary response of the supercrystal,wepropose an exact linear parametric method of solving the nonlinearsteady-state problem, whileto address the supercrystal optical dynamicsqualitatively, we put forward a novel method to cal-culate the bifurcationdiagram of the system. Analyzing the dynamics, we demonstrate thatthesupercrystal can exhibit multistability, periodic and aperiodicself-oscillations, and chaotic behavior,depending on parameters of thesupercrystal and excitation conditions. The effects originate fromthe interplayof the intrinsic nonlinearity of quantum dots and the retarded inter-dotdipole-dipoleinteraction. The latter provides a positive feedback which resultsin the exotic supercrystal opticaldynamics. These peculiarities of thesupercrystal optical response open up a possibility for all-opticalapplicationsand devices. In particular, an all-optical switch, a tunable generator of THzpulses (inself-oscillating regime), a noise generator (in chaotic regime), anda tunable bistable mirror can bedesigned.
