For real-world deployment, waveguide sources offer optimum compatibility with fiber networks and can be embedded in hybrid integrated modules. Here, we present what we believe to be the first chip-size fully integrated fiber-coupled heralded single photon source (HSPS) module based on a hybrid integration of a nonlinear lithium niobate waveguide into a polymer board. Photon pairs at 810 nm (signal) and 1550 nm (idler) are generated via parametric down-conversion pumped at 532 nm in the LiNbO3 waveguide. The pairs are split in the polymer board and routed to separate output ports. The module has a size of (2 × 1) cm^2 and is fully fiber-coupled with one pump input fiber and two output fibers. We measure a heralded second-order correlation function of g_h(2)=0.05 with a heralding efficiency of η_h=3.5% at low pump powers","lang":"eng"}],"publication":"Optics Express","title":"Fiber-coupled plug-and-play heralded single photon source based on Ti:LiNbO3 and polymer technology","publication_identifier":{"issn":["1094-4087"]},"user_id":"44252","year":"2023","author":[{"id":"44252","first_name":"Christian","full_name":"Kießler, Christian","last_name":"Kießler"},{"full_name":"Conradi, Hauke","last_name":"Conradi","first_name":"Hauke"},{"first_name":"Moritz","full_name":"Kleinert, Moritz","last_name":"Kleinert"},{"full_name":"Quiring, Viktor","last_name":"Quiring","first_name":"Viktor"},{"id":"216","first_name":"Harald","full_name":"Herrmann, Harald","last_name":"Herrmann"},{"full_name":"Silberhorn, Christine","last_name":"Silberhorn","id":"26263","first_name":"Christine"}],"status":"public","_id":"46644","article_type":"original","publication_status":"published","doi":"10.1364/oe.487581","date_created":"2023-08-23T07:20:06Z","citation":{"ieee":"C.
