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…
High-fidelity initialization of long-lived quantum dot hole spin qubits by reduced fine-structure splitting
Alistair J. Brash, Luis M. P. P. Martins, Feng Liu +4
We demonstrate an on-demand hole spin qubit initialization scheme meeting four key requirements of quantum information processing: fast initialization (1/e ~ 100 ps), high fidelity…
Correlated Photon-Pair Generation in a Highly Nonlinear Fiber Using Spontaneous FWM
Álvaro J. Almeida, Luís M. Martins, Nuno A. Silva +2
We generate 1550 nm correlated photon pairs through the spontaneous four-wave mixing (SpFWM) process in a highly nonlinear fiber (HNLF). The pair source quality generation is evalu…
