Query: Nonlinear optical response of a two-dimensional quantum-dot
  supercrystal: Emerging multistability, periodic and aperiodic
  self-oscillations, chaos, and transient chaos   We conduct a theoretical study of the nonlinear optical response of a
two-dimensional semi-conductor quantum dot supercrystal subjected to a
quasi-resonant continuous wave excitation. Aconstituent quantum dot is odeled
as a three-level ladder-like system (comprising the ground, theone-exciton, and
the bi-exction states). To study the stationary response of the supercrystal,
wepropose an exact linear parametric method of solving the nonlinear
steady-state problem, whileto address the supercrystal optical dynamics
qualitatively, we put forward a novel method to cal-culate the bifurcation
diagram of the system. Analyzing the dynamics, we demonstrate that
thesupercrystal can exhibit multistability, periodic and aperiodic
self-oscillations, and chaotic behavior,depending on parameters of the
supercrystal and excitation conditions. The effects originate fromthe interplay
of the intrinsic nonlinearity of quantum dots and the retarded inter-dot
dipole-dipoleinteraction. The latter provides a positive feedback which results
in the exotic supercrystal opticaldynamics. These peculiarities of the
supercrystal optical response open up a possibility for all-opticalapplications
and devices. In particular, an all-optical switch, a tunable generator of THz
pulses (inself-oscillating regime), a noise generator (in chaotic regime), and
a tunable bistable mirror can bedesigned.
