Abstract

We have measured the time correlation of pairs of photons from a neon discharge source limited by a 2 micrometer diameter aperture. [1] Light from this small source aperture is coherent over a wide range of angles so that the second order correlation function shows an excess counting rate (the Hanbury Brown-Twiss effect) over a wide range of propagation directions. This geometry allows the measured two-photon counting rate to be compared with the predictions of a maximum entropy density matrix over a wider range of angles than was previously possible.
