Phys. Rev. Lett. 98, 153603 (2007) [4 pages]Measuring Photon Antibunching from Continuous Variable Sideband SqueezingReceived 4 September 2006; published 13 April 2007 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 antibunching statistic of g(2)(0)=0.11±0.18. © 2007 The American Physical Society URL:
