Title:
Implementation of a Two-Photon Michelson Interferometer for Quantum-Optical Coherence Tomography
Issue Date:

Abstract:
Time-domain Optical Coherence Tomography (OCT) is an imaging technique that provides information about the infernal structure of a sample. It makes use of classical light in conjunction with conventional interferometers. A quantum versión of OCT, called Quantum-Optical Coherence Tomography (QOCT), has been developed in previous years. QOCT uses entangled photon pairs in conjunction with two-photon interferometers. QOCT improves depth resolution and offers more information about the optical properties of the sample. However, the current implementation of QOCT is not competitive with its classical counterpart because of the low efficiency of the current sources and detectors that are required for its implementation. We analyzed the feasibility of QOCT using a Michelson interferometer that can be adapted to the state of the art in entangled photon sources and detectors. Despite of its simplicity, no current implementations of QOCT have been done with this interferometer. This thesis develops the theory of the two-photon Michelson interferometer applied in QOCT. It describes the elements that characterizes the coincidences interferogram and support the theory with experimental measurements. We found that as long as the spectral bandwidth of the entangled photons is smaller than their central frequency, the Michelson interferometer can be successfully used for QOCT. In addition, we found that the degree of entanglement between the photons can be calculated from the coincidences interferogram. The two-photon Michelson interferometer provides another possibility for QOCT with the advantages of simplicity, performance and adaptability. The resolution of the interferometer can be improved using ultrabroadband sources of entangled photons, e.g. photonic fibers. In addition, we can study the implementation of photonnumber resolving detectors in order to remove the detection of coincidences that is used for detecting entangled photon pairs.
