Magneto-optics of a charge-tunable quantum dot: Observation of a negative diamagnetic shift
Giora Peniakov, Ayal Beck, Eilon Poem +5
We present magneto-optical studies of a self-assembled semiconductor quantum dot in neutral and positively charged states. The diamagnetic shifts and Zeeman splitting of many well-…
Determinstic Generation of a Quantum Dot-Confined Triexciton and its Radiative Decay via Three-Photon Cascade
E. R. Schmidgall, I. Schwartz, L. Gantz +3
Semiconductor quantum dots (QDs) have potential applications in quantum information processing due to the fact that they are potential on-demand sources of single and entangled pho…
Optically induced rotation of a quantum dot exciton spin
E. Poem, O. Kenneth, Y. Kodriano +4
We demonstrate control over the spin state of a semiconductor quantum dot exciton using a polarized picosecond laser pulse slightly detuned from a biexciton resonance. The control…
Two-photon- photoluminescence excitation spectroscopy of single quantum-dots
Y. Benny, Y. Kodriano, E. Poem +3
We present experimental and theoretical study of single semiconductor quantum dots excited by two non-degenerate, resonantly tuned variably polarized lasers. The first laser is tun…
Radiative cascade from quantum dot metastable spin-blockaded biexciton
Y. Kodriano, E. Poem, N. H. Lindner +5
We detect a novel radiative cascade from a neutral semiconductor quantum dot. The cascade initiates from a metastable biexciton state in which the holes form a spin-triplet configu…
Polarization memory in single Quantum Dots
E. Poem, S. Khatsevich, Y. Benny +4
We measured the polarization memory of excitonic and biexcitonic optical transitions from single quantum dots at either positive, negative or neutral charge states. Positive, negat…
