Phase Reversal Diffraction in incoherent light

TL;DR

This paper demonstrates experimentally that phase reversal diffraction can occur in incoherent chaotic light through first-order field correlation, without the need for negatively refracting media or phase-conjugate interfaces.

Contribution

It introduces a novel method to observe phase reversal diffraction using chaotic light, expanding understanding of wave propagation phenomena.

Findings

Phase reversal diffraction observed in incoherent chaotic light.

Experimental results align with theoretical analysis.

Demonstrates phase reversal without traditional negative refraction devices.

Abstract

Phase reversal occurs in the propagation of an electromagnetic wave in a negatively refracting medium or a phase-conjugate interface. Here we report the experimental observation of phase reversal diffraction without the above devices. Our experimental results and theoretical analysis demonstrate that phase reversal diffraction can be formed through the first-order field correlation of chaotic light. The experimental realization is similar to phase reversal behavior in negatively refracting media.
