  bibo_abstract:
  - "<jats:p>Broadband quantum light is a vital resource for quantum metrology and
    spectroscopy applications such as quantum optical coherence tomography or entangled
    two photon absorption. For entangled two photon absorption in particular, very
    high photon flux combined with high time-frequency entanglement is crucial for
    observing a signal. So far these conditions could be met by using high power lasers
    driving degenerate, type 0 bulk-crystal spontaneous parametric down conversion
    (SPDC) sources. This naturally limits the available wavelength ranges and precludes
    deterministic splitting of the generated output photons. In this work we demonstrate
    an integrated two-colour SPDC source utilising a group-velocity matched lithium
    niobate waveguide, reaching both exceptional brightness 1.52⋅10<jats:sup>6</jats:sup>pairssmWGHz
    and large bandwidth (7.8 THz FWHM) while pumped with a few mW of continuous wave
    (CW) laser light. By converting a narrow band pump to broadband pulses the created
    photon pairs show correlation times of Δ<jats:italic>τ</jats:italic> ≈ 120 fs
    while maintaining the narrow bandwidth Δ<jats:italic>ω</jats:italic><jats:sub>\r\n
    \     <jats:italic>p</jats:italic>\r\n    </jats:sub> ≪ 1 MHz of the CW pump light,
    yielding strong time-frequency entanglement. Furthermore our process can be adapted
    to a wide range of central wavelengths.</jats:p>@eng"
