A New Test of Bell’s Inequality Using Optical Interference

  • J. D. Franson
Conference paper


A new form of two-photon interferometry1 that is dependent upon nonlocal correlations between a pair of photons is currently under investigation. These two-photon interference effects violate Bell’s inequality without any dependence upon photon polarization and are thus of fundamental interest. They may have practical applications in such areas as coherent Raman spectroscopy as well.
