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

Optical characterization of ZnSe/ZnMgSSe microdisks with embedded CdSe quantum dots
TL;DR: In this article, photoluminescence (PL) studies of ZnSe/ZnMgSSe microdisks with embedded CdSe quantum dots were reported. But the results were limited to a single layer of self-assembled quantum dots.

The design and fabrication of an electrically activated photonic crystal microcavity laser
TL;DR: Kolodziejski et al. as discussed by the authors described the design and fabrication of a microcavity laser utilizing multiple photonic crystal mirrors, which is well suited for integrated optics for many reasons.

The effect of scaling microlasers on modal noise
TL;DR: In this article, low-power microlasers with optimized design and operating conditions were used to exhibit modal noise comparable to large incoherent multimodal devices in Gb/s multimode fiber interconnects.

Laser eigenvalue, coherence time, Q-factor, and linewidth
Markus Pollnau,Marc Eichhorn +1 more
TL;DR: In this paper, the authors generalize the theory of continuous-wave laser by considering spontaneous emission in the photon rate equation and relate the laser coherence time, Q-factor and linewidth to the passive-resonator parameters, thereby unifying resonator and laser theory.

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.
