High Purcell factor generation of coherent on-chip single photons
F. Liu, A. J. Brash, J. O'Hara +11
On-chip single-photon sources are key components for integrated photonic quantum technologies. Semiconductor quantum dots can exhibit near-ideal single-photon emission but this can…

Dynamic vibronic coupling in InGaAs quantum dots
A. J. Brash, L. M. P. P. Martins, A. M. Barth +7
The electron-phonon coupling in self-assembled InGaAs quantum dots is relatively weak at low light intensities, which means that the zero-phonon line in emission is strong compared…

Ultrafast Depopulation of a Quantum Dot by LA-phonon-assisted Stimulated Emission
F. Liu, L. M. P. Martins, A. J. Brash +5
We demonstrate ultrafast incoherent depopulation of a quantum dot from above to below the transparency point using LA-phonon-assisted emission stimulated by a redshifted laser puls…
