Optical detection of the electron spin resonances of G centers in silicon
Félix Cache, Krithika V. R., Tobias Herzig +8
Color centers in silicon are emerging as promising platforms for quantum technologies. Among them, the G center has attracted considerable interest owing to its bright telecom O-ba…

A single optically detectable tumbling spin in silicon
Félix Cache, Yoann Baron, Baptiste Lefaucher +9
We demonstrate single spin spectroscopy of a fluorescent tumbling defect in silicon called the G center, behaving as a pseudo-molecule randomly reorienting itself in the crystallin…

Bright and pure single-photon source in a silicon chip by nanoscale positioning of a color center in a microcavity
Baptiste Lefaucher, Yoann Baron, Jean-Baptiste Jager +8
We present an all-silicon source of near-infrared linearly-polarized single photons, fabricated by nanoscale positioning of a color center in a silicon-on-insulator microcavity. Th…
