Entangled-photon ellipsometry

Ayman F. Abouraddy, Kimani C. Toussaint, Alexander V. Sergienko +2 more

Performing reliable measurements in optical metrology, such as those needed in ellipsometry, requires a calibrated source and detector, or a well-characterized reference sample. We present a novel interferometric technique to perform reliable ellipsometric measurements. This technique relies on the use of a nonclassical optical source, namely, polarization-entangled twin photons generated by spontaneous parametric downconversion from a nonlinear crystal, in conjunction with a coincidence-detection scheme. Ellipsometric measurements acquired with this scheme are absolute, i.e., they require neither source nor detector calibration, nor do they require a reference.

Entangled-photon ellipsometry

Alexander V. Sergienko, Ayman F. Abouraddy, Kimani C. Toussaint +2 more

We present a novel quantum interferometric technique to perform ellipsometric measurements. Classical ellipsometric measurements are limited in their accuracy by virtue of the need for an absolutely calibrated source and detector. Mitigating this limitation requires the use of a well-characterized reference sample. Our technique relies on the use of a non-classical optical source, namely polarization-entangled twin photons generated by spontaneous parametric down-conversion from a nonlinear crystal, in conjunction with a coincidence-detection scheme. We have demonstrated that entangled-photon ellipsometry eliminates the necessity of constructing an interferometer altogether and is thereby self-referencing. The underlying physics that leads to this remarkable result is the presence of fourth-order (coincidence) quantum interference of the photon pairs in conjuction with polarization entanglement.
