Abstract:

Laser speckles have become a fundamental component of the modern optics-research toolbox. Not only are speckle patterns the basis of numerous imaging techniques, but they are also employed to generate optical potentials for cold atoms and colloidal particles. The ability to manipulate a speckle patterns spatial intensity correlations, particularly long-range non-localones, is essential in numerous applications. A typical fully-developed speckle pattern, however, possesses only short-ranged local intensity correlations which are determined by the spatial field correlations. Here, we experimentally demonstrate and theoretically develop a general method for creating fully-developed speckles with strong non-local intensity correlations. The functional form of the spatial intensity correlations can be arbitrarily tailored without altering the field correlations. Our approach provides a versatile and utilitarian framework for enhancing and controlling non-local correlations in speckle patterns.
