Birefringence and scattering characterization using polarization sensitive quantum optical coherence tomography

Vitaly Sukharenko, Siméon Bikorimana, R. Dorsinville

Polarization sensitive quantum optical coherence tomography (PS-QOCT) is used to characterize birefringence, scattering/absorption and path length differences in a flat transparent plastic sample. In this Letter, we present the first, to the best of our knowledge, experimental technique of PS-QOCT imaging and characterization of a birefringent material. Polarization sensitive coincidence rate of the entangled photons measured for each pixel and the 2D cross-sectional images are reconstructed. The technique described in this work has many potential applications in the characterization of micro and nano structures, including biological samples.

Polarization-Sensitive Quantum Optical Coherence Tomography: Birefringence Profiles of Biological Samples

Vitaly Sukharenko, R. Dorsinville

Polarization-sensitive quantum optical coherence tomography (PS-QOCT) is used to image and characterize birefringence effects in biological samples. Entangled photons are generated via spontaneous parametric down-conversion and split into a reference arm and a sample arm of a Mach Zehnder interferometer. Interferometric patterns between two entangled photons reveal information about tissue birefringence. Biological tissue samples are imaged and characterized, and their quantum interference patterns and birefringence profiles are presented.

Polarization-sensitive quantum-optical coherence tomography

We set forth a polarization-sensitive quantum-optical coherence tomography (PS-QOCT) technique that provides axial optical sectioning with polarization-sensitive capabilities. The technique provides a means for determining information about the optical path length between isotropic reflecting surfaces, the relative magnitude of the reflectance from each interface, the birefringence of the interstitial material, and the orientation of the optical axis of the sample. PS-QOCT is immune to sample dispersion and therefore permits measurements to be made at depths greater than those accessible via ordinary optical coherence tomography. We also provide a general Jones matrix theory for analyzing PS-QOCT systems and outline an experimental procedure for carrying out such measurements.

Quantum optical coherence tomography and applications to biological imaging

Mark C. Booth, Giovanni Di Giuseppe, Bahaa E. A. Saleh +2 more

We propose a method of quantum optical coherence tomography (QOCT) that utilizes a nonclassical source of entangled photons (signal and idler). By using type-II spontaneous parametric downconversion, where signal and idler photons emerge with orthogonal polarizations, it is possible to probe the biological sample using a polarization-entangled state.
