Bending motion of photons in Young's double-slit

Abstract

The investigation of the interference phenomenon of Young's double-slit using a single photon is an epoch-making experiment demonstrating the mystery of quantum mechanics, but the details have not yet been clarified. We have developed a method for observing the behavior of photons near the double-slit using a multimode optical fiber to obtain a two-dimensional map of photon motion. Quantitative analysis of the directional motion revealed that the directional change was related to the derivative of the electric field and was uniquely determined by the direction of photon motion.
