Reduction of radiative lifetime and slow-timescale spectral diffusion in InGaN polarized single-photon sources
Tong Wang, Tongtong Zhu, Tim J. Puchtler +6
Non-polar (11-20) a-plane quantum dots (QDs) are strong candidates for both > 200 K on-chip ultrafast polarized single-photon generation and the investigation of high temperature s…
An ultrafast polarised single photon source at 220 K
Tong Wang, Tim J. Puchtler, Tongtong Zhu +4
A crucial requirement for the realisation of efficient and scalable on-chip quantum communication is an ultrafast polarised single photon source operating beyond the Peltier coolin…
Ultrafast, polarized, single-photon emission from m-plane InGaN Quantum Dots on GaN nanowires
Tim J. Puchtler, Tong Wang, Christopher X. Ren +4
We demonstrate single photon emission from self-assembled m-plane InGaN quantum dots (QDs) embedded on the side-walls of GaN nanowires. A combination of electron microscopy, cathod…
Experimental and theoretical analyses of strongly polarized photon emission from non-polar InGaN quantum dots
Tong Wang, Tim J. Puchtler, Saroj Kanta Patra +7
We present a comprehensive investigation of the polarization properties of non-polar a-plane InGaN quantum dots (QDs) and their origin with statistically significant experimental d…
Strong exciton-photon coupling with colloidal nanoplatelets in an open microcavity
Lucas C. Flatten, Sotirios Christodoulou, Robin K. Patel +6
Colloidal semiconductor nanoplatelets exhibit quantum size effects due to their thickness of only few monolayers, together with strong optical band-edge transitions facilitated by…
Electrically tunable organic-inorganic hybrid polaritons with monolayer WS2
Lucas C. Flatten, David M. Coles, Zhengyu He +4
Exciton-polaritons are quasiparticles consisting of a linear superposition of photonic and excitonic states, offering potential for nonlinear optical devices. The excitonic compone…
Excited exciton and biexciton localised states in a single quantum ring
H. D. Kim, K. Kyhm, R. A. Taylor +6
We observe excited exciton and biexciton states of localised excitons in an anisotropic quantum ring, where large polarisation asymmetry supports the presence of a crescent-like lo…
Asymmetry of localised states in a single quantum ring: polarization dependence of excitons and biexcitons
H. D. Kim, K. Kyhm, R. A. Taylor +4
We performed spectroscopic studies of a single GaAs quantum ring with an anisotropy in the rim height. The presence of an asymmetric localised state was suggested by the adiabatic…
