Nevertheless, compatibility with certain quantum light sources and superconducting detectors requires operation under cryogenic conditions. We characterize alterations in phase-matching and mode guiding of a non-degenerate spontaneous parametric down-conversion process emitting around 1556 nm and 950 nm, under cryogenic conditions. Despite the effects of pyroelectricity and photorefraction, the spectral properties match our theoretical model. Nevertheless, these effects cause small but significant variations within and between cooling cycles. These measurements provide a first benchmark against which other nonlinear photonic integration platforms, such as thin-film lithium niobate, can be compared."}],"intvolume":"        33","date_updated":"2025-12-12T12:13:45Z","publication_identifier":{"issn":["1094-4087"]},"project":[{"_id":"171","name":"TRR 142; TP C07: Hohlraum-verstärkte Parametrische Fluoreszenz mit zeitlicher Filterung unter Verwendung integrierter supraleitender Detektoren"}]}
