Description
|
Artistic depiction of a single erbium ion being implanted into a silicon-based optical nanocavity. A focused ion beam (top) delivers individual Er ions with nanometer precision, while a laser (left) laterally couples light into the nanocavity to excite the ion. The excited erbium ion emits single photons in the telecom C-band, enabling scalable quantum light sources compatible with existing fiber networks.
