Key Points

The photon-pair source achieves high spectral purity of 99.9% alongside polarization-entanglement of up to 0.99.
Signal photon operates at 794-nm, targeting Tm-based quantum memory, while the idler photon is at approximately 1283-nm for telecom applications.
This technology leverages a CMOS-compatible platform, enhancing integration possibilities in quantum systems and devices.
The results highlight significant potential for improving quantum networking and communication architectures using solid-state memory.

Implication

This system demonstrates high spectral purity and polarization entanglement, suggesting new avenues for quantum networking applications.

Abstract

We propose a CMOS-compatible photon-pair source based on SiN offering simultaneous high spectral-purity ( ≥ 99.9%) and polarization-entanglement (concurrence upto 0.99), with the signal photon at 794-nm for addressing Tm-based quantum memory and the idler at ∼ 1283-nm (telecom O-band).
