PREDICTIONS OF VIOLATIONS OF BELL’S INEQUALITY IN AN S-PORT HOMODYNE DETECTOR

4 violation of Bell’s inequality is predicted in the system of correlated electromagnetic field modes present in an optical 8-port homodyne detector. In this system all of the field modes are of the same polarization, and the correlated field modes are analyzed wth phase sensitive homodyne detectors. Since Bell’s work [ I] was published a number of experiments [2-l 11 have been undertaken to test Bell’s inequality. Some of these experiments made use of correlated spin systems [ IO,1 1] such as the ones described by Bohm [ 121 and Bell [ 11. How-ever, the system used in the majority of these ex-periments [ 2-91 consisted of a pair of photons cor-related via their polarizations. The correlated two-photon state is essentially the same as the spin sin-glet state. Such a state can be produced in the two photons emitted successively in a cascade atomic de-cay. The devices used to analyze the pair of photon
