Towards Hybrid Integration of Laser-Written Integrated Photonic Circuits and Single-Photon Avalanche Diode Arrays
We report the direct coupling of femtosecond laser-written photonic circuits and SPAD arrays, showcasing unitary coupling efficiency and 41% detection efficiency, offering a promising route for scalable, high-performance detection systems beyond traditional cryogenic-based systems.
