TL;DR: In this paper, spontaneous emission of an atom is not an immutable property of the atom but can be altered by modification of the vacuum field fluctuations surrounding the atom, and it has been shown that spontaneous emission can be enhanced by embedding the quantum wells between A1As/A1GaAs distributed Bragg reflectors.

TL;DR: In this paper, the authors investigated the electrical control of the lasing wavelength in two-section quantum dot laser and showed that by changing the optical loss in the absorber section, the control of ground state (GS) and excited state (ES) lasing thresholds and output powers is achieved.
Abstract: The electrical control of the lasing wavelength in two-section quantum dot lasers is investigated. By changing the optical loss in the absorber section, the control of the ground-state (GS) and excited-state (ES) lasing thresholds and output powers is achieved. Additionally, a complex self-pulsation dynamics with simultaneous oscillations of the GS and ES intensities is observed. The experimental results are well explained in the framework of a rate equation model.

TL;DR: In this paper, a Fabry-Perot microcavity enclosing a thin diamond membrane at cryogenic temperatures is proposed to enhance resonant emission of single nitrogen-vacancy centers by allowing spectral and spatial tuning while preserving the optical properties observed in bulk diamond.
Abstract: We report on the fabrication and characterization of a Fabry-Perot microcavity enclosing a thin diamond membrane at cryogenic temperatures. The cavity is designed to enhance resonant emission of single nitrogen-vacancy centers by allowing spectral and spatial tuning while preserving the optical properties observed in bulk diamond. We demonstrate cavity finesse at cryogenic temperatures within the range of F ¼ 4000–12 000 and find a sub-nanometer cavity stability. Modeling shows that coupling nitrogen-vacancy centers to these cavities could lead to an increase in remote entanglement success rates by three orders of magnitude.

TL;DR: In this paper, the dynamics of a quantum dot embedded in a three-dimensional microcavity in the strong coupling regime was studied, in which the quantum dot exciton has an energy close to the frequency of a confined cavity mode.
Abstract: 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.

TL;DR: In this article, an organic photodetector (OPD) structure was demonstrated in which the active layers and a thick optical spacer are sandwiched between two metallic electrodes, forming a Fabry-Perot resonant cavity.
