TL;DR: In this article, the optical absorption of excitonic states in a linear array of quantum dots in the presence of electric and magnetic fields aligned with the array axis was investigated and the results for a large range of external field values and for different geometric confinement regimes were obtained.
Abstract: We report calculations of the optical absorption of excitonic states in a linear array of quantum dots in the presence of electric and magnetic fields aligned with the array axis. In this system, in addition to the quantum dot geometric confinement and the Stark confinement, it is also present the confinement induced by the magnetic field that modifies the lateral characteristic energies of the system. The competing action between the effects of the electron-hole correlation and the different mechanisms of quantum confinement produces a rich structure in the spectrum. We show results for a large range of external field values and for different geometric confinement regimes.

12 May 2000TL;DR: The influence of four-particle correlations on the nonlinear optics of a semiconductor microcavity is determined by a pump-and-probe investigation and it is shown that the coherent nonlinearity is dominated by biexciton-exciton interactions beyond the Hartree-Fock approximation.
Abstract: Summary form only given. Recent pump-and-probe measurements performed on the exciton-polariton in GaAs-based microcavities have been interpreted in terms of contributions due to biexcitons. Inspired by these initial hints we investigated a microcavity containing a single 5 nm ZnSe quantum well which provides large biexciton binding energies and small exciton linewidths. As a result we report here the first direct observation of a spectrally isolated, pump-induced resonance due to polariton-biexciton transitions in a microcavity.

12 Jan 2001TL;DR: In this article, a resonant microcavity display with a substrate, a phosphor active region and front and rear reflectors is proposed to create a standing or treaveling eledtromagnetic wave to enhance the light transmission.
Abstract: A resonant microcavity display (20) having microcavity with a substrate (25), a phosphor active region (50) and front and rear reflectors (30 and 60). The front and rear reflectors may be spaced to create either a standing or treaveling eledtromagnetic wave to enhance the efificenty of the light transmission.

TL;DR: In this article, two families of two-dimensional photonic crystal microlasers are classified according to the approach used for the lateral confinement of the light (via trapping photons in a microcavity or via slowing down optical modes at an extreme of the dispersion characteristics), with a special emphasis on the characteristics of devices below and at laser threshold.
Abstract: We investigate the two families of two-dimensional photonic crystal microlasers that are classified according to the approach used for the lateral confinement of the light (via trapping photons in a microcavity or via slowing down optical modes at an extreme of the dispersion characteristics), with a special emphasis on the characteristics of devices below and at laser threshold. The respective merits and drawbacks of the two families are analyzed in the light of an analytical modeling and of experimental results obtained on a variety of microlaser devices. The latter are processed in an InP-membrane heterostructure bounded onto silica on silicon. Promising prospects, which are expected from the combination of the two confinement approaches, are discussed.

TL;DR: In this paper, the authors demonstrate the application of an optomechanical oscillator (OMO) as a high-resolution mass sensor, where the coupling between high-Q optical and mechanical modes of a single optical microcavity results in narrow linewidth mechanical oscillation driven by the radiation pressure of the circulating optical power.
Abstract: We demonstrate the application of an optomechanical oscillator (OMO) as a high-resolution mass sensor. The coupling between high-Q optical and mechanical modes of a single optical microcavity results in narrow linewidth mechanical oscillation driven by the radiation pressure of the circulating optical power. The oscillation frequency can be monitored upon detection of the modulated transmitted optical power. Therefore the optical wave plays a dual role as both the driving power and a sensitive probe. The narrow oscillation linewidth, combined with the sensitivity of the mechanical resonance to mass changes, makes OMO an excellent candidate for all-optical mass sensing. Experimental results and theoretical analysis show that OMO can function as a compact, low-power mass sensor with sub-pg sensitivity.
