Ci. Um et al., PHOTON STATISTICS AND PHASE FLUCTUATION OF MACH-ZEHNDER INTERFEROMETER WITH 2 DOPAS, Journal of the Korean Physical Society, 33(2), 1998, pp. 131-135
A homodyning Mach-Zehnder interferometer with two degenerated optical
parametric amplifiers is analyzed. The photon statistics of the entang
led state of two correlated squeezed states is shown briefly in terms
of the Mandel's Q parameter. The mean-square fluctuation of the phase
shift in the interferometer is analyzed in consideration of the signal
-to-noise ratio of the output photocurrent. They are analyzed as funct
ions of the gains of the crystals and the input intensity.
