Quantum Noise Measurements in Degenerate Four-Wave Mixing
Recent work has highlighted the potential applications of two-photon coherent states (TCS), also known as squeezed states, in optical communications and precision measurements. These states have non-classical noise statistics. Their predicted generation schemes include the degenerate parametric amplifier, degenerate four-wave mixing (DFWM), and multi-photon optical bistability. The preceding generation schemes have been analyzed to varying degrees of approximation, but no experimental observation of TCS has been reported as yet. In this paper we describe an experiment measuring the quantum statistics of light that has undergone DFWM to look for squeezed-state generation via this process.
