Observation of positive–negative sub-wavelength interference without intensity correlation calculation

Abstract We report an experimental demonstration of positive–negative sub-wavelength interference without correlation. Typically, people can achieve sub-wavelength effects with correlation measurement no matter by using bi-photon or thermal light sources. In this paper, we adopt a thermal light sour...
