Experimental test of the delayed single-photon self-interference effect
A modified version of the delayed single-photon self-interference experiment is performed using a sample of Pr:Y2SiO5 for detecting the interference pattern. Instead of using a beam splitter and two spatially separated paths for the light to travel towards the material, acousto-optic modulators are used to create two light pulses and let the pulses travel along the same path towards the material.
