| Abstract: | The spontaneous emission from a quantum dot embedded in a bi-sphere microcavity is analyzed theoretically. By taking full account of the photon degree of freedom, we derive theoretically the constant of coupling between the quantum dot and the cavity as well as the radiation damping constants, which are used in the conventional cavity QED approach. In addition, we show that the power spectrum of the spontaneous emission at a local observation point is strongly affected by the photon Green function. |
