Ultranarrow linewidth room-temperature single-photon source from perovskite quantum dot embedded in optical microcavity
Amit R. Dhawan, Tristan Farrow, Ashley Marshall +5
Ultranarrow bandwidth single-photon sources operating at room-temperature are of vital importance for viable optical quantum technologies at scale, including quantum key distributi…
Design of free-space couplers for suspended triangular nano-beam waveguides
J. P. Hadden, Cobi Maynard, Daryl M. Beggs +2
Photonic waveguides with triangular cross section are being investigated for material systems such as diamond, glasses and gallium nitride, which lack easy options to create conven…
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…
Resonantly pumped bright-triplet exciton lasing in caesium lead bromide perovskites
Guanhua Ying, Tristan Farrow, Atanu Jana +9
The surprising recent observation of highly emissive triplet-states in lead halide perovskites accounts for their orders-of-magnitude brighter optical signals and high quantum effi…
Imaging non-radiative point defects buried in quantum wells using cathodoluminescence
Thomas Weatherley, Wei Liu, Vitaly Osokin +5
Crystallographic point defects (PDs) can dramatically decrease the efficiency of optoelectronic semiconductor devices, many of which are based on quantum well (QW) heterostructures…
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…
