A Tuneable Telecom Wavelength Entangled Light Emitting Diode Deployed in an Installed Fibre Network

Z. Xiang, J. Huwer, et al.

This groundbreaking research presented by Zi-Heng Xiang and colleagues introduces a fully electrically operated telecom entangled light emitting diode (ELED) that can tune its wavelength over 25 nm. Successfully integrated into an existing fiber network, it shows an impressive ability to multiplex single entangled photons with classical data traffic while achieving entanglement fidelities exceeding 94%.

Abstract

This paper presents a fully electrically operated telecom entangled light emitting diode (ELED) with over 25 nm wavelength tuneability, successfully deployed in an installed fiber network. The device, operating at 1310.00 nm, demonstrates multiplexing of single entangled photons with classical data traffic, achieving entanglement fidelities exceeding 94% over a city's installed fiber network.
