Dynamics of the excitations of a quantum dot in a microcavity

J. I. Perea, Diego Porras, C. Tejedor

We study the dynamics of a quantum dot embedded in a three-dimensional microcavity in the strong coupling regime in which the quantum dot exciton has an energy close to the frequency of a confined cavity mode. Under the continuous pumping of the system, the confined electron and hole can recombine either by spontaneous emission through a leaky mode or by stimulated emission of a cavity mode that can escape from the cavity. The numerical integration of a master equation including all these effects gives the dynamics of the density matrix. By using the quantum regression theorem, we compute the first- and second-order coherence functions required to calculate the photon statistics and the spectrum of the emitted light. Our main result is the determination of a range of parameters in which a state of cavity modes with Poissonian or sub-Poissonian (nonclassical) statistics can be built up within the microcavity. Depending on the relative values of pumping and rate of stimulated emission, either one or two peaks close to the excitation energy of the dot and/or to the natural frequency of the cavity are observed in the emission spectrum. The physics behind these results is discussed.

Stimulated Emission Behavior of Single Quantum Dot in Microcavity

Chang-qi Cao

A system consisted of a three-level quantum dot coupled to a single mode of an optical microcavity is investigated.Using the numerical calculation method,the net stimulated emission dynamical evolution with the variation of the coupling strength between the quantum dot and the single mode of the optical microcavity is studied,which is based on quantum-optical master equations. The effect of the decay rate between the laser levels on the net stimulated emission is also studied. When the coupling strength between the quantum dot and the single mode of the optical cavity is larger, the net stimulated emission is prone to a saturation curve sooner. These saturation curves get to a limit value with the increasing value of the coupling strength sooner. The net stimulated emission curves show the opposite law with the increasing value of the decay rate between the laser levels.
