Ultrashort dead time of photon-counting InGaAs avalanche photodiodes
A. R. Dixon, J. F. Dynes, Z. L. Yuan +3
We report a 1.036 GHz gated Geiger mode InGaAs avalanche photodiode with a detection dead time of just 1.93 ns. This is demonstrated by full recovery of the detection efficiency tw…
Evolution of entanglement within classical light states
R. Mark Stevenson, Andrew J. Hudson, Anthony J. Bennett +4
We investigate the evolution of quantum correlations over the lifetime of a multi-photon state. Measurements reveal time-dependent oscillations of the entanglement fidelity for pho…
Coherence of an Entangled Exciton-Photon State
A. J. Hudson, R. M. Stevenson, A. J. Bennett +6
We study the effect of the exciton fine-structure splitting on the polarisation-entanglement of photon pairs produced by the biexciton cascade in a single quantum dot. The entangle…
Single electron-spin memory with a semiconductor quantum dot
Robert J. Young, Samuel J. Dewhurst, R. Mark Stevenson +6
We show storage of the circular polarisation of an optical field, transferring it to the spin-state of an individual electron confined in a single semiconductor quantum dot. The st…
Electrically addressing a single self-assembled quantum dot
D. J. P. Ellis, A. J. Bennett, P. Atkinson +2
We report on the use of an aperture in an aluminum oxide layer to restrict current injection into a single self-assembled InAs quantum dot, from an ensemble of such dots within a l…
