All light has structure, but only recently has it been possible to control it in all its degrees of
freedom and dimensions, fuelling fundamental advances and applications alike. Here we …

Structured light, especially beams carrying orbital angular momentum (OAM), has gained
much interest due to its unique amplitude and phase structures. In terms of communication …

Orbital angular momentum (OAM), which describes tailoring the spatial physical dimension
of light waves into a helical phase structure, has given rise to many applications in optical …

Optical aberrations place fundamental limits on the achievable resolution with focusing and
imaging. In the context of structured light, optical imperfections and misalignments and …

Modes of propagation through an optical system are generally defined as the eigensolutions
of the wave equation in the system. When propagation occurs through complicated or highly …

With the ever-increasing demand for data and the radio frequency spectrum becoming
congested, free space optics (FSO) may find a niche for situations where fiber is too …

Structured light is routinely used in free-space optical communication channels, both
classical and quantum, where information is encoded in the spatial structure of the mode for …

Atmospheric turbulence can cause critical problems in many applications. To effectively
avoid or mitigate turbulence, knowledge of turbulence strength at various distances could be …

Structured light has become topical of late, where controlling light in all its degrees of
freedom has offered novel states of light long predicted, enhanced functionality in …

There is a growing interest in structured light, especially orbital angular momentum (OAM)
beams, due to its unique amplitude and phase structure. Multiple orthogonal OAM beams …
