Measurement and modification of biexciton-exciton time correlations

Tobias Huber, Ana Predojević, Hashem Zoubi +3 more

Photons which are generated in a two-photon cascade process have an underlying time correlation since the spontaneous emission of the upper level populates the intermediate state. This correlation leads to a reduction of the purity of the photon emitted from the intermediate state. Here we characterize this time correlation for the biexciton-exciton cascade of an InAs/GaAs quantum dot. We show that the correlation can be reduced by tuning the biexciton transition in resonance to a planar distributed Bragg reflector cavity. The enhanced and inhibited emission into the cavity accelerates the biexciton emission and slows down the exciton emission thus reduces the correlation and increases the purity of the exciton photon. This is essential for schemes like creating time-bin entangled photon pairs from quantum dot systems.

Slow light using tunneling-induced transparency in triple semiconductor conical quantum dot molecule

Nooralhuda S.Yaqoob, Sabah M. M. Ameen

The electronic states of InAs/GaAs quantum dot has investigated for triple conical quantum dots molecule (CQDM). We calculated Eigen energies as a function of external voltage. Tunneling-induced transparency (TIT) in triple InAs/GaAs quantum dots using tunneling instead of pump laser, analogous to electromagnetically induced transparency (EIT) in atomic systems, has studied. The interdot quantum coupling strength is tuned by static electric fields. For parameters appropriate to a 100 Gbits/s optical network, slow down factor (SDF) as 109 can be achieved. The scheme is expected to be useful to construct a variable semiconductor optical buffer based on TIT in triple InAs/GaAs quantum dots controlled by electric fields.
