Complementarity relationship between coherence and path distinguishability in an interferometer based on induced coherence
Gerard J. Machado, Lluc Sendra, Adam Vallés +1
We consider an interferometer based on the concept of induced coherence, where two photons that originate in different second-order nonlinear crystals can interfere. We derive a co…

Optical Coherence Tomography with a nonlinear interferometer in the high parametric gain regime
Gerard J. Machado, Gaetano Frascella, Juan P. Torres +1
We demonstrate optical coherence tomography based on an SU(1,1) nonlinear interferometer with high-gain parametric down-conversion. For imaging and sensing applications, this schem…

Frequency correlation requirements on the biphoton wavefunction in an induced coherence experiment between separate sources
Arturo Rojas-Santana, Gerard J. Machado, Dorilian Lopez-Mago +1
There is renewed interest in using the coherence between beams generated in separate down-converter sources for new applications in imaging, spectroscopy, microscopy and optical co…
