This is because changes in the length of an "arm" produces a phase shift in the light, which in turn shifts the interference ...

Coherence measurements with the two-photon Michelson interferometer

WebJul 2, 2013 · Interferometric photon-correlation measurements, which correspond to the second-order intensity cross correlations between the two output ports of an unbalanced Michelson (or Mach-Zehnder) interferometer, are sensitive to both amplitude and phase fluctuations of an incoming beam of light. WebThe squeezing can be detected at the output ports of the interferometer either by direct detection or by measuring the spectrum of the difference current. We use the Hudson-Parthasarathy equation to model the global evolution. It can describe the scattering of photons and the resulting radiation pressure interaction on the quantum oscillator. je m\\u0027enfuis
