Geometric phases have attracted considerable attention in recent years, due to their
capability of arbitrary beam shaping in a most efficient and compact way, while traditional …

We demonstrate a 200-Gbit/s space-division multiplexing system using two Laguerre–
Gaussian (LG) beams with different radial indices (LG_ℓ= 0, p= 0 and LG_ℓ= 0, p= 1). With a …

Structured light in the short-wavelength regime opens exciting avenues for the study of
ultrafast spin and electronic dynamics. Here, we demonstrate theoretically and …

The concept of entanglement is so synonymous with quantum mechanics that the prefix
“quantum” is often deemed unnecessary; there is after all only quantum entanglement. But …

Free space optics (FSO) systems use the atmosphere as a propagation medium. However, a
common problem is atmospheric turbulence, including fog, rain, and haze that emerges …

Tailored complex optical fields, may find applications in optical manipulation, imaging,
microscopy, quantum information processing, and optical communications. Here, we focus …

Mode-division multiplexing over fibers has attracted increasing attention over the last few
years as a potential solution to further increase fiber transmission capacity. In this paper, we …

Here we employ both dynamic and geometric phase control of light to produce radially
modulated vector-vortex modes, the natural modes of optical fibers. We then measure these …

Twisted light carrying orbital angular momentum (OAM), which features a helical phase front,
has shown its potential applications in diverse areas, especially in free-space optical (FSO) …

When structured light is propagated through the atmosphere, turbulence results in modal
scattering and distortions. An extensively studied example is that of light carrying orbital …
