Query: Observation of Anticorrelation with Classical Light in a Linear Optical
  System   Two-photon anticorrelation is observed when laser and pseudothermal light
beams are incident to the two input ports of a Hong-Ou-Mandel interferometer,
respectively. The spatial second-order interference pattern of laser and
pseudothermal light beams is reported. Temporal Hong-Ou-Mandel dip is also
observed when these two detectors are at the symmetrical positions. These
results are helpful to understand the physics behind the second-order
interference of light.
