TLDR
In this paper, the rate equations for a microcavity semiconductor laser are solved and the steady-state behavior of the laser and some of its dynamic characteristics are investigated, and it is shown that by manipulating the mode density and the spontaneous decay rates of the cavity modes, the threshold gain can be decreased and the modulation speed can be improved.Abstract:
The rate equations for a microcavity semiconductor laser are solved and the steady-state behavior of the laser and some of its dynamic characteristics are investigated. It is shown that by manipulating the mode density and the spontaneous decay rates of the cavity modes, the threshold gain can be decreased and the modulation speed can be improved. However, in order to fully exploit the possibilities which the modification of the spontaneous decay opens up, the active material volume in the cavity must be smaller than a certain value. Threshold current using different definitions, population inversion factor, L-I curves, linewidth, and modulation response are discussed. >read more

Inhibited Spontaneous Emission
TL;DR: The radiative properties of an atom in a cavity differ fundamentally from the atom's radiative property in free space as mentioned in this paper. But the cavity causes slight shifts in the energies of the atom, analogous to radiative shifts.

Observation of cavity-enhanced single-atom spontaneous emission
TL;DR: It has been observed that the spontaneous-emission lifetime of Rydberg atoms is shortened by a large ratio when these atoms are crossing a high-Q$ superconducting cavity tuned to resonance with a millimeter-wave transition between adjacent Ryd Berg states as mentioned in this paper.

Inhibited spontaneous emission by a Rydberg atom.
TL;DR: Spontaneous radiation by an atom in a Rydberg state is inhibited by use of parallel conducting planes to eliminate the vacuum modes at the transition frequency.
