从相敏相干性到超聚束的二阶干涉
From phase-sensitive coherence to super-bunching second-order interference
摘要
Abstract
Here conjugate symmetry of Fourier transform is applied to the production of a novel phase-sensitive symmetric pseudo-thermal light source by manipulating the spatial phase structure of an incident light field,characterized by the same amplitude but reversed-phase at spatially symmetric locations.Such chaotic light still reflects the bunching effect of thermal light(with a peak correlation coefficient of 2),and produces an anomalously spatial super-bunching effect in second-order interference experiments,along with a theoretical peak of 3.Compared with other light sources,such as pseudo-thermal light,it is experimentally verified that the phase-sensitive symmetric thermal light can break through the upper limit of visibility of second-order interference fringes from 1/3 to 1/2 of the original one.This work therefore reveals an inner connection between phase-sensitive coherence and super-bunching correlation,which can be utilized to boost the visibility of various correlation-enabled applications.This work provides a new approach to generate super-bunching pseudo-thermal light.关键词
