Abstract
We present an optical coherence tomography scheme with undetected photons in an SU(1,1) interferometer based on an integrated nonlinear waveguide. We achieve an axial resolution of < 0.2mm in the time domain and implement differential pumping to compensate for losses in the interferometer.
