Propagation of Nonclassical Light through a Semiconductor Microcavity

Abstract

We extend recently developed schemes for field quantization in absorbing dielectric media with local susceptibilities to dielectric systems described by a nonlocal susceptibility, in order to quantize the electromagnetic field in quantum wells embedded in planar semiconductor microcavities. As an application of the formalism, we analyze the effects of the propagation through a semiconductor microcavity on a continuous-mode squeezed coherent state. In particular, we calculate the variance of the field transmitted through the microcavity in the case of strong coupling regime for different detection schemes, as a function of the detuning, the exciton–photon coupling and the exciton homogeneous broadening.

Electromagnetic field quantization in quantum confined systems

Omar Di Stefano

We extend recently developed schemes for field quantization in absorbing dielectric media with local susceptibilities to dielectric systems described by a non local susceptibility. The method is applied to the cases of a semiconductor quantum well embedded in infinite barriers and embedded in planar semiconductor microcavities. As an application of the formalism, we analyze the effects of the propagation through a semiconductor microcavity (MC) on a continuous-mode squeezed coherent state.

Electromagnetic-field quantization in absorbing confined systems

Omar Di Stefano, Salvatore Savasta, R. Girlanda

We quantize the electromagnetic field in an absorbing resonant medium with translation symmetry broken along one direction. In this case the general polarization of the material system is driven by the field via a nonlocal complex susceptibility. We extend recently developed schemes for field quantization in absorbing dielectric media with local susceptibilities to dielectric systems described by a nonlocal susceptibility. Dissipation inside the medium is described by considering the coupling of polarization quanta of the system with the reservoir oscillators in the usual Langevin approach. The method is applied to the case of a semiconductor quantum well embedded in infinite barriers. Expressions for the electromagnetic-field operators are obtained in the different spatial regions and the spatial and frequency dependencies of the vacuum-field fluctuations are calculated.

External-field effect on quantum features of radiation emitted by a quantum well in a microcavity

Eyob Alebachew Sete, Sumanta Das, Hichem Eleuch

We consider a semiconductor quantum well in a microcavity driven by coherent light and coupled to a squeezed vacuum reservoir. By systematically solving the pertinent quantum Langevin equations in the strong-coupling and low-excitation regimes, we study the effect of exciton-photon detuning, external coherent light, and the squeezed vacuum reservoir on vacuum Rabi splitting and on quantum statistical properties of the light emitted by the quantum well. We show that the exciton-photon detuning leads to a shift in polariton resonance frequencies and a decrease in fluorescence intensity. We also show that the fluorescent light exhibits quadrature squeezing, which predominately depends on the exciton-photon detuning and the degree of the squeezing of the input field.

Generation of nonclassical light upon resonant excitation of a semiconductor microcavity

M. V. Lebedev, A.L. Parakhonsky, A. A. Demenev

Strong correlations in the fluctuations of the intensity of emission from a semiconductor microcavity under resonant laser excitation are observed. The intensity correlation function exhibits an unusual oscillatory behavior with an unexpectedly long oscillation period and decay time. The visibility of the correlation function reaches 0.81. Long oscillation times are attributed to the Rabi frequency characterizing weak coupling between the electromagnetic field of the semiconductor microcavity mode and long-lived exciton states localized by the random potential of the quantum well. For a laser excitation power density of 400 W/cm 2 , the power density of the radiation emitted by the microcavity is 12 W/cm 2 , which corresponds to the total flux of nonclassical light of 1.5 × 10 15 photons/s from an excited spot 50 μm in diameter. Thus, a microcavity can serve as a bright emitter of nonclassical light.

Cavity QED effects in semiconductor microcavities

Hichem Eleuch, Jean-Michel Courty, Gaétan Messin +2 more

A theoretical investigation of cavity QED effects in semiconductor microcavities containing quantum wells is presented. A model Hamiltonian is used to derive equations of motion for the quantum photon and exciton fields in the cavity. Quantum effects such as squeezing and antibunching are predicted in the light field going out of the cavity under irradiation by a coherent laser field, if exciton-phonon scattering is weak enough. Exciton-phonon scattering is shown to destroy the nonclassical effects and to yield excess noise in the output field.

Quantum optical effects in semiconductor microcavities

E. Giacobino, Jean‐Philippe Karr, Gaétan Messin +2 more

Investigations of quantum effects in semiconductor quantum-well microcavities interacting with laser light in the strong-coupling regime are presented. Modifications of quantum fluctuations of the outgoing light are expected due to the non-linearity originating from coherent exciton–exciton scattering. In the strong-coupling regime, this scattering translates into a four-wave mixing interaction between the mixed exciton–photon states, the polaritons. Squeezing and giant amplification of the polariton field and of the outgoing light field fluctuations are predicted. However, polariton–phonon scattering is shown to yield excess noise in the output field, which may destroy the non-classical effects. Experiments demonstrate evidence for giant amplification due to coherent four-wave mixing of polaritons. Noise reduction below the thermal noise level was also observed.
