Layer-poled lithium niobate nanophotonic waveguides for efficient wavelength conversion and photon-pair generation
We demonstrate a lithium niobate nanophotonic waveguide with layer-wise ferroelectric domain inversion through electrical poling, achieving modal-phase-matched second-harmonic generation with a normalized efficiency up to 4615% W -1 cm -2 .
