Silicon quantum emitters emitting in the optical telecommunication range for scalable quantum photonic circuits — •Yonder Berencén — Helmholtz-Zentrum Dresden-Rossendorf, Institute of Ion Beam Physics and Materials Research, 01328 Dresden, Germany

Silicon has recently emerged as a promising host for single-photon emitters operating at telecom wavelengths, offering a pathway toward scalable quantum photonic technologies on a CMOS-compatible platform. In this invited talk, I will provide an overview of the most relevant intrinsic and extrinsic-based quantum emitters in silicon, including the W, G, T, and C centers as well as erbium. I will discuss their optical and spin properties, deterministic creation via broad-beam ion implantation and focused ion beam implantation, and recent progress toward realizing spin-optical interfaces in the optical telecom bands. Particular emphasis will be placed on single-emitter spectroscopy, demonstration of optically detected magnetic resonance (ODMR) in silicon at telecom wavelengths, and the integration opportunities enabled by silicon*s mature photonic and electronic fabrication ecosystem. Finally, I will outline a roadmap toward fully monolithic silicon quantum photonic integrated circuits that combine single emitters with on-chip photonic routing and a groundbreaking approach for silicon-based single-photon detectors at the telecom range.
