Free-space optics naturally offers multiple-channel communications and sensing exploitable
in many applications. The different optical beams will, however, generally be overlapping at …

In technologies operating at light wavelengths for wireless communication, sensor networks,
positioning, and ranging, a dynamic coherent control and manipulation of light fields is an …

Atmospheric turbulence can generate scintillation or beam wandering phenomena that
impairs free space optical (FSO) communication. In this paper, we propose and demonstrate …

Free-space communication links are severely affected by atmospheric turbulence, which
causes degradation in the transmitted signal. One of the most common solutions to …

A multimode optical receiver for free space optical communications (FSOC) based on a
photonic lantern and adaptive optics coherent beam combining (CBC) of the lantern's single …

In free-space optical communications that use both amplitude and phase data modulation
(for example, in quadrature amplitude modulation (QAM)), the data are typically recovered …

Multi-aperture receiver with optical combining architecture is an effective approach to
overcome the turbulent atmosphere effect on the performance of the free-space optical …

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 …

We present a GPU accelerated toolbox for shaping the light propagation through multimode
fibre using a spatial light modulator (SLM). The light is modulated before being coupled to …

The next generation free-space optical communications infrastructure will need to support a
wide variety of space-to-ground links. As a result of the limited size, weight, and power on …
