  bibo_abstract:
  - Integrated photon-pair sources, providing scalability solutions, are crucial for
    large-scale realizations of quantum photonic technologies. Their traditional fabrication
    techniques, such as etching, are often complex, require long development cycles,
    and are resource inefficient in case of fabrication imperfections or failures.
    The two-photon polymerization (2PP) technique can offer a rapid, efficient, and
    reproducible alternative for the fabrication of integrated photonic devices. Here,
    we demonstrate an integrated photon-pair source based on a 2PP-defined strip-loaded
    waveguide on a periodically poled thin-film lithium niobate (TFLN) platform. The
    device generates photon pairs through type-II spontaneous parametric down-conversion
    (SPDC), employing first-order quasi-phase matching (QPM) with TM-polarized excitation
    light. The device achieves an on-chip pair generation rate of 4.357 MHz and a
    coincidence-to-accidental ratio (CAR) of ∼404. To prove the flexibility and versatility
    of the fabrication technique, the waveguides were erased from the LN substrate
    and reprinted, reaching comparable performance. This work demonstrates the potential
    of 2PP as a rapid production technique for high-performance integrated photon-pair
    sources, offering a practical solution to the limitations of traditional fabrication
    techniques and showcasing both reproducibility of the fabrication and the reusability
    of the substrate.@eng
