Hong-Ou-Mandel Photon Bunching (2D)

Top-down 2D companion to the Hong-Ou-Mandel two-photon interference lab: fire photons into a 50:50 beamsplitter and read the coincidence-click statistics as timing delay, visibility and coherence time change.

This 2D companion drives the same coincidence statistics as the 3D version through a flat top-down view: two photons converge on a 50:50 beamsplitter from opposite sources, and the coincidence probability P(Δt) = ½·[1 − V·exp(−(Δt/τ)²)] decides — trial by trial — whether they bunch out the same detector or split between the two. A live scatter-and-theory graph beneath the stage accumulates every trial so the Hong-Ou-Mandel dip emerges from the statistics in real time instead of being drawn in advance.
