Abstract
We present a novel interferometric technique for performing ellipsometric m easurements. This technique relies on the use of a nonclassical optical sou rce, namely, polarization-entangled twin photons generated by spontaneous p arametric downconversion from a nonlinear crystal, in conjunction with a co incidence-detection scheme, Ellipsometric measurements acquired with this s cheme are absolute; i.e., they do not require source and detector calibrati on.
