  text: <jats:p>This work reports a fully guided setup for single-mode squeezing on
    integrated titanium-indiffused periodically poled nonlinear resonators. A continuous-wave
    laser beam is delivered and the squeezed field is collected by single-mode fibers;
    up to −3.17(9) dB of useful squeezing is available in fibers. To showcase the
    usefulness of such a fiber-coupled device, we applied the generated squeezed light
    in a fiber-based phase sensing experiment, showing a quantum enhancement in the
    signal-to-noise ratio of 0.35 dB. Moreover, our investigation of the effect of
    photorefraction on the cavity resonance condition suggests that it causes system
    instabilities at high powers.</jats:p>
