A hemispherical, high-solid-angle optical micro-cavity for cavity-QED studies
Guoqiang Cui, J. M. Hannigan, R. Loeckenhoff +8
We report a novel hemispherical micro-cavity that is comprised of a planar integrated semiconductor distributed Bragg reflector (DBR) mirror, and an external, concave micro-mirror…
Many-Body Dynamics and Exciton Formation Studied by Time-Resolved Photoluminescence
W. Hoyer, C. Ell, M. Kira +6
The dynamics of exciton and electron-hole plasma populations is studied via time-resolved photoluminescence after nonresonant excitation. By comparing the peak emission at the exci…
Direct Optical Excitation of Quantum-Degenerate Exciton States in Semiconductors
M. Kira, S. W. Koch, G. Khitrova +1
Quantum electrodynamic calculations predict that truly incoherent light can be used to efficiently generate quantum-degenerate exciton population states. Resonant incoherent excita…
Excitonic Photoluminescence in Semiconductor Quantum Wells: Plasma versus Excitons
S. Chatterjee, C. Ell, S. Mosor +7
Time-resolved photoluminescence spectra after nonresonant excitation show a distinct 1s resonance, independent of the existence of bound excitons. A microscopic analysis identifies…
