We consider nonlinear dynamics of a system of interacting photons and excitons driven by a resonantly exciting light field. Using the linear stability analysis for nonlinear coupled equations of photon and exciton operators we investigated that, besides the usual unstable domain which is a negative slope branch, there are other unstable ones in the leftmost and rightmost sides of the lower and upper branches of the frequency-density bistable curves. Numerical study shows that the system has very rich information on the instability nature and a self-oscillation process leading to chaos can occur in these unstable domains.

The study of time development is indispensable for a system of excitons and bi-excitons at high density because this exists only as a transient state. Here we study theoretically the population dynamics of excitons and bi·excitons both under the. pulse and steady excitations where photons and phonons emitted in the chemical processes of this system can be considered as the irrelevant external system. Under the opposite condition where the radiation field composes the relevant system, the laser action due to the radiative decay of bi ·excitons is discussed.
