In recent years, free space optical (FSO) communication has gained significant importance
owing to its unique features: large bandwidth, license free spectrum, high data rate, easy …

Optical wireless communication (OWC) refers to transmission in unguided propagation
media through the use of optical carriers, ie, visible, infrared (IR), and ultraviolet (UV) bands …

This article presents an overview of optical wireless (OW) communication systems that
operate both in the short-(personal and indoor systems) and the long-range (outdoor and …

The concept of deep-space optical communications was formulated shortly after the
invention of lasers. The promise of laser communications, high data rate delivery with …

In order to achieve multi-gigabit transmission (projected for 2020) for the use in
interplanetary communications, the usage of large number of time slots in pulse-position …

Free-space laser communication systems have the potential to provide flexible, high-speed
connectivity suitable for long-haul intersatellite and deep-space links. For these applications …

This article presents an efficient error-control code (ECC) and modulation for an optical
communications channel. The coded modulation is designed to support NASA's Mars Laser …

For free-space optical (FSO) links in turbulent atmosphere modeled by gamma-gamma
distributions, an approximation of the pairwise error probability (PEP) was derived for on-off …

Free-space laser communication systems use optical-fiber-based technology such as optical
amplifiers, receivers, and high-speed modulators. In these systems using single-mode …
