Speckle patterns are used in a broad range of applications including microscopy, imaging,
and light–matter interactions. Tailoring speckles' statistics can dramatically enhance their …

We experimentally generate three-dimensional speckles with customized intensity statistics.
By appropriately modulating the phase front of a laser beam, the far-field speckles can …

We present results on the second-harmonic generation using nondiffracting speckle fields in
the fundamental frequency to pump a nonlinear medium to obtain the sum-frequency …

Controlling random light is a key enabling technology that pioneered statistical imaging
methods like speckle microscopy. Such low-intensity illumination is especially useful for bio …

The structured beams especially with spatially varying phase distribution have attracted
tremendous attention in both physics and engineering. Recently, studies have shown that …

Localization phenomena during transport are typically driven by disordered scalar
potentials. Here, we predict a universal pseudospin localization phenomenon induced by a …

We report on a speckle field that is non-Rayleigh, nondiffracting, and an exact solution to the
scalar Helmholtz equation. We have shown that these fields can be directly optimized to a …

The generation of speckle patterns via random matrices, statistical definitions, or apertures
may not always result in optimal outcomes. Issues such as correlation fluctuations in low …

Speckle with non-Rayleigh amplitude distribution has significant research value in imaging
and measurement using structured illumination. However, existing speckle customizing …

We customized light speckle fields with both super-bunching and non-diffracting properties,
accordingly named as the super-bunching, non-diffracting (SP-ND) speckle fields, by …
