Spectrally resolved Hong–Ou–Mandel interferometry for quantum-optical coherence tomography

Abstract

In this paper, we revisit the well-known Hong-Ou-Mandel (HOM) effect in which two photons, which meet at a beamsplitter, can interfere destructively, leading to null in coincidence counts. In a standard HOM measurement, the coincidence counts across the two output ports of the beamsplitter are monitored as the temporal delay between the two photons prior to the beamsplitter is varied, resulting in the wellknown HOM dip. We show, both theoretically and experimentally, that by leaving the delay fixed at a particular value while relying on spectrally-resolved coincidence photon-counting, we can reconstruct the HOM dip, which would have been obtained through a standard delay-scanning, non-spectrally-resolved HOM measurement. We show that our numerical reconstruction procedure exhibits a novel dispersion cancellation effects, to all orders. We discuss how our present work can lead to a drastic reduction in the time required to acquire a HOM interferogram, and specifically discuss how this could be of particular importance for the implementation of efficient quantum-optical coherence tomography devices.

Spectrally resolved NOON state interference

“…This phase dependent feature is totally different from the case of HOM interference [16,19,20], which is phase independent. The spectrally resolved HOM interference has been applied for the situation in which the phase insensitivity is required, e.g., the generation and distribution of frequency-entangled qudits [20], efficient quantum-optical coherence tomography [27].…”

Quantum interferometric two-photon excitation spectroscopy

“…The most remarkable outcome of this study is the fact that we provide a connection between sum-frequency intensity and N00N-state interference pattern. In addition to quantum inter-ferometric spectroscopy, which extracts spectral signals from temporal measurements, spectral-domain optical coherence tomography that detects the thickness induced by a transparent material may also be accessible [54,55]. This might motivate the development of novel applications of full-field optical coherence tomography and three-dimensional imaging.…”
