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 …

Optical communication is an integral part of the modern economy, having all but replaced
electronic communication systems. Future growth in bandwidth appears to be on the horizon …

Transverse spatial modes of light offer a large state-space with interesting physical
properties. For exploiting these special modes in future long-distance experiments, the …

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

The spatial structuring of optical fields is integral within many next generation optical
metrology and communication techniques. A verifiable physical model of the propagation of …

Atmospheric turbulence over long horizontal paths perturbs phase and can also cause
severe intensity scintillation in the pupil of an optical communications receiver, which limits …

Partially coherent beams hold much promise in free-space optical communications for their
resistance to the deleterious effects of atmospheric turbulence. We describe the basic …

Spatially structured optical fields have been used to enhance the functionality of a wide
variety of systems that use light for sensing or information transfer. As higher-dimensional …

The free-space transfer of high-fidelity optical signals between remote locations has many
applications, including both classical and quantum communication, precision navigation …

We design an optical feedback network making use of machine learning (ML) techniques
and demonstrate via simulations its ability to correct for the effects of turbulent propagation …
