Paper Abstract

Nonlinear structures of a coherent state of Wannier-Mott excitons sustained by resonant optical pumping in semiconductors are investigated both theoretically and numerically. The structures can originate from both instability with respect to spatial periodic stratification and finite amplitude disturbances, when initial homogeneous state is stable with respect to the small fluctuations. Spectrum of collective excitations and stability of the structures are discussed. Transformations of structures are demonstrated.
