This paper introduces a novel class of inseparable coherent structures through theory and experiment. These structures vanish in a completely coherent environment but can be maintained in a coexistent state of extreme incoherence and full coherence. The analysis reveals an interesting association between the magnitude and the phase of the coherent structure, displaying both synergy and opposition. The work uncovers the inner mechanism of inseparable coherent structures and expands the horizon for optical twist.
A novel, to the best of our knowledge, class of coherent structures of inseparability, incorporating phases asymmetrically cross-coupled by two position vectors, is introduced in theory and experiment. These phases disappear in the environment of complete coherence, but the vanishment is avoidable in the coexistent state of extreme incoherence and full coherence. The radiated beams intrinsically possess a controllable rotation but undergo an intermediate process quite different from the twisted Gaussian Schell-model beams. Analysis shows a novel association between the magnitude and the phase of the coherent structure which displays both synergy and opposition. Our work further reveals the inner mechanism of the inseparable coherent structures and extends a new horizon for the optical twist. (C) 2022 Optica Publishing Group
