The closed-loop optimization framework for entangled photon sources autonomously controls alignment, temperature, and pump polarization to ensure stable operation. By combining a crossed-crystal PPKTP configuration with a Sagnac interferometer, the system maintains intrinsic phase stability while maximizing spectral brightness. This automation overcomes manual tuning bottlenecks, ensuring reproducible performance for quantum communication networks in real-world environments.
