Three-photon excitation of quantum two-level systems
Viviana Villafañe, Bianca Scaparra, Manuel Rieger +8
We demonstrate that semiconductor quantum dots can be excited efficiently in a resonant three-photon process, whilst resonant two-photon excitation is highly suppressed. Time-depen…
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…
Effects of microstructure and growth conditions on quantum emitters in Gallium Nitride
Minh Nguyen, Tongtong Zhu, Mehran Kianinia +5
Single-photon emitters in gallium nitride (GaN) are gaining interest as attractive quantum systems due to the well-established techniques for growth and nanofabrication of the host…
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…
