Journal ArticleDOI
Stimulated emission from nitrogen-vacancy centres in diamond
Jan Jeske,Desmond W. M. Lau,Xavier Vidal,Liam P. McGuinness,Philipp Reineck,Brett C. Johnson,Marcus W. Doherty,Jeffrey C. McCallum,Shinobu Onoda,Fedor Jelezko,Takeshi Ohshima,Thomas Volz,Jared H. Cole,Brant C. Gibson,Andrew D. Greentree +14 more
TL;DR: The results open the possibility of diamond lasers based on NV− centres, tuneable over the phonon sideband, which broadens the applications of NV− magnetometers from single centre nanoscale sensors to a new generation of ultra-precise ensemble laser sensors, which exploit the contrast and signal amplification of a lasing system.
Journal ArticleDOI
A room temperature single photon source in silicon carbide
Stefania Castelletto,Brett C. Johnson,Viktor Ivády,N. Stavrias,Takashi Umeda,Adam Gali,Takeshi Ohshima +6 more
TL;DR: In this article, the first observation of stable single photon sources in an electronic and photonic device-friendly material, silicon carbide (SiC), was reported, which is a viable material for implementing quantum communication, computation and light-emitting diode technologies.
Journal ArticleDOI
A review on single photon sources in silicon carbide.
TL;DR: Key findings in single-photon generation from deep level defects in silicon carbide (SiC) are summarized and the significance of these individually addressable centers for emerging quantum applications is highlighted.
Journal ArticleDOI
Single-photon emitting diode in silicon carbide.
Alexander Lohrmann,Naoya Iwamoto,Zoltán Bodrog,Stefania Castelletto,Takeshi Ohshima,Timothy J. Karle,Adam Gali,Adam Gali,Steven Prawer,Jeffrey C. McCallum,Brett C. Johnson +10 more
TL;DR: The fabrication of bright single-photon emitting diodes that display fully polarized output, superior photon statistics, and stability in both continuous and pulsed modes, all at room temperature are demonstrated.
Journal ArticleDOI
Detection of atomic spin labels in a lipid bilayer using a single-spin nanodiamond probe
Stefan H. E. Kaufmann,David Simpson,Liam T. Hall,Viktor Perunicic,Philipp Senn,Philipp Senn,Steffen Steinert,Liam P. McGuinness,Brett C. Johnson,Takeshi Ohshima,Frank Caruso,Joerg Wrachtrup,Robert E. Scholten,Paul Mulvaney,Lloyd C. L. Hollenberg +14 more
TL;DR: The detection of gadolinium spin labels in an artificial cell membrane under ambient conditions using a single-spin nanodiamond sensor is demonstrated and opens a pathway for in situ nanoscale detection of dynamical processes in biology.
