  text: We demonstrate the integration of amorphous tungsten silicide superconducting
    nanowire single-photon detectors on titanium in-diffused lithium niobate waveguides.
    We show proof-of-principle detection of evanescently coupled photons of 1550 nm
    wavelength using bidirectional waveguide coupling for two orthogonal polarization
    directions. We investigate the internal detection efficiency as well as detector
    absorption using coupling-independent characterization measurements. Furthermore,
    we describe strategies to improve the yield and efficiency of these devices.
