  - "<jats:p>\r\n                    The development of practical sensors for optical
    coherence tomography (OCT) with undetected photons requires miniaturization via
    integration. To be practical, these sensors must exhibit a large spectral bandwidth
    and a high brightness, which are linked to a high axial resolution and a sufficient
    signal-to-noise ratio, respectively. Here, we combine these requirements in a
    scheme for OCT measurements with undetected photons based on nonlinear\r\n                    <a:math

    the performance benchmarks of the commonly used SU(1,1) scheme in comparison to
    an induced-coherence scheme and find that the latter is actually better suited
    when implementing measurements with undetected photons in integrated systems.
    In both schemes, we perform pump-gain optimization and OCT measurements with undetected
    photons with an axial resolution as low as\r\n                    <d:math xmlns:d=\"http://www.w3.org/1998/Math/MathML\"
