Abstract

We experimentally investigate interference pattern formation in second-order intensity correlation considering the polarization state of pseudothermal light beams. By placing a double slit in one of the beams it is shown that the interference pattern depends on the polarization state of the light after the slits. When different parts of the double slit are aligned in different beams, we found that the interference is always observed, even for the case where the beams are orthogonally polarized. Our results are analyzed using a filtering process and indistinguishability of paths interpretation. Extensions of our findings to massive particles are also discussed.

Interference pattern formation in the second-order intensity correlation with beams orthogonally polarized

Itamar Vidal, D. P. Caetano, C. Olindo +2 more

Considering the polarization state of the pseudothermal light beams, we demonstrate that the nonlocal second-order interference pattern formation does not depend on the polarization of the beams crossing the different parts of a distributed double-slit.

Nonlocal Double-Slit Interference with Pseudothermal Light

Lu Gao, Jun Xiong, Lu-Fang Lin +3 more

We perform a nonlocal double-slit interference experiment with pseudothermal light. The experimental result exhibits a typical double-slit interference fringe in the intensity correlation measurement, in agreement with the theoretical analysis by means of the property of the second-order spatial correlation of field.

Observation of complementarity in the macroscopic domain

De-Zhong Cao, Jun Xiong, Hua Tang +3 more

Complementarity is usually considered as a phenomenon of microscopic systems. In this paper, we report an experimental observation of complementarity in correlated double-slit interference with a pseudothermal light source. The thermal light beam is divided into test and reference beams which are correlated with each other. The double slit is set in the test arm, and an interference pattern can be observed in the intensity correlation between the two arms. The experimental results show that the disappearance of the interference fringe depends on whether which-path information is gained through the reference arm. The experiment therefore shows complementarity occurring in the macroscopic domain.

The first- and second-order temporal interference between thermal and laser light

Jianbin Liu, Huaibin Zheng, Hui Chen +3 more

The first- and second-order temporal interference between two independent thermal and laser light beams is discussed by employing the superposition principle in Feynman's path integral theory. It is concluded that the first-order temporal interference pattern can not be observed by superposing two independent thermal and laser light beams, while the second-order temporal interference pattern can be observed in the same condition. These predictions are experimentally verified by employing pseudothermal light to simulate thermal light. The relationship between the indistinguishability of alternatives and photons is analyzed. The conclusions are helpful to understand the interference of different kinds of light and the difference between the coherence properties of thermal and laser light.
