    Tunneling spectroscopy for quantum well excitons (1997)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 70 (1997), S. 1986-1988 
    Details
    ISSN: 1077-3118

    Topics: Physics
    Notes: We have demonstrated a technique of directly measuring the exciton binding energy and the valence band split in the quantum well through a tunneling process. We have also measured the emission efficiency of quantum well heavy-hole excitons and light-hole excitons into the normal direction. © 1997 American Institute of Physics.

    Observation of dressed-exciton oscillating emission over a wide wavelength range in a semiconductor microcavity (1995)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 66 (1995), S. 1107-1109

    Topics: Physics
    Notes: We have observed the dressed-exciton oscillating emission in the time domain and the associated spectral splitting in the frequency domain from a GaAs single quantum well microcavity over a very broad range of cavity resonant wavelengths. The spectral splitting and temporal oscillation period have been measured to be nearly constant over two orders of magnitude variation of pump intensity, which confirms the linear bosonic feature of Wannier excitons in the weak excitation regime. © 1995 American Institute of Physics.

    Vacuum field induced mixing of light and heavy-hole excitons in a semiconductor microcavity (1996)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 69 (1996), S. 3465-3467

    Topics: Physics
    Notes: Measurements in a semiconductor microcavity reveal the coupling between light- and heavy-hole excitons that is mediated by the electromagnetic vacuum. Three polariton modes constructed from superpositions of heavy-hole excitons, light-hole excitons, and photons are observed. The experimental results are in good agreement with the theory of three-coupled bosonic modes, each coupled to an independent reservoir. © 1996 American Institute of Physics.

    Quantum limit for the atom-light interferometer (1995)
    Springer

    Notes: Abstract The standard quantum limit is calculated for the atom-light interferometer. It is shown that the smallest detectable phase is $$\delta \phi _{\min } = \frac{1}{2}[N_{atoms} + 4N_{photons} )/N_{atoms} N_{photons} ]^{1/2} .$$ Therefore, in practical experiments, the accuracy is limited by the square root of the number of atoms. We propose a novel correlated atom-photon state interferometer which makes a transition to the Heisenberg limit, δφmin ∝ 1/N atoms, as the atoms approach a Bose condensate. Such an interferometer may serve as a sensitive probe of the onset of Bose condensation. Finally, we point out that the correlated atom-photon state preparation scheme we propose may be used in a different way to approach the Heisenberg limit for non-Bose-condensed atoms.

    Phonon-polariton interaction in a microcavity (1995)

    Notes: Summary The linewidth of the microcavity exciton polariton is studied by onresonant and off-resonant photoluminescences. The two main contributions to the linewidth are caused by radiative loss and phonon scattering. The oscillator strength is found to be unmodified by the exciton-phonon coupling. Comparison is made between theory and experiment.
