We present a technique for measuring the second-order coherence function g(2)(τ) of light using a Hanbury-Brown Twiss intensity interferometer modified for homodyne detection. The experiment was performed entirely in the continuous variable regime at the sideband frequency of a bright carrier field. We used the setup to characterize g(2)(τ) for thermal and coherent states, and investigated its immunity to optical loss. We measured g(2)(τ) of a displaced squeezed state, and found a best anti-bunching statistic of g(2)(0) = 0.11 ± 0.18.
