摘要

Abstract

Integrated photon-pair sources are crucial for scalable photonic quantum systems. Thin-film lithium niobate is a promising platform for on-chip photon-pair generation through spontaneous parametric down-conversion (SPDC). However

the device implementation faces practical challenges. Periodically poled lithium niobate (PPLN)

despite enabling flexible quasi-phase matching

suffers from poor fabrication reliability and device repeatability

while conventional modal phase matching (MPM) methods yield limited efficiencies due to inadequate mode overlaps. Here

we introduce a layer-poled lithium niobate (LPLN) nanophotonic waveguide for efficient photon-pair generation. It leverages layer-wise polarity inversion through electrical poling to break spatial symmetry and significantly enhance nonlinear interactions for MPM

achieving a notable normalized second-harmonic generation (SHG) conversion efficiency of 4615% W

. Through a cascaded SHG and SPDC process

we demonstrate photon-pair generation with a normalized brightness of 3.1 × 10

Hz nm

in a 3.3 mm long LPLN waveguide

surpassing existing on-chip sources under similar operating configurations. Crucially

our LPLN waveguides offer enhanced fabrication reliability and reduced sensitivity to geometric variations and temperature fluctuations compared to PPLN devices. We expect LPLN to become a promising solution for on-chip nonlinear wavelength conversion and non-classical light generation

with immediate applications in quantum communication

networking

and on-chip photonic quantum information processing.
