Free-space Optics for Communications at Sea

Optical Fiber Communication Conference (OFC) 2022, 2022
We discuss our free-space-optical communication system, specifically exploring tradeoffs in pointing, acquisition, and tracking design and the use of retransmission to mitigate the impact of turbulence-induced fades.

Feedforward-based free-space optical communication

Applied Optics, 2021
We propose to use 1-bit feedforward information at the free-space optical (FSO) receiver to improve its error performance. We concentrate upon M -ary pulse amplitude modulation (PAM) signaling and design an error-optimal PAM constellation for providing efficient 1-bit feedforward information to the receiver.

Prospects and Challenges of Free Space Optical Communications

2018
Free space optical (FSO) transmission is a technology which uses a narrow laser beam to transmit the signal from the source to the destination through the free space. Although it has various advantages, a laser beam propagating through the atmosphere is subjected to different kind of disturbances causing the attenuation of the signal and, in some ...

Optical communication in free space

SPIE Proceedings, 2008
The success of free-space optical links operating indoors or in the atmosphere or deep space shows a good perspective of the technology. There is no doubt that free-space technology is ready for wide practical application. Optical links have several advantages in comparison with radio links, namely high transmission rates and high security.

Adaptive cooperation for free space optical communications

Telecommunication Systems, 2020
In this paper, we propose a new Adaptive Cooperation (AC) protocol for Free Space Optical (FSO) communications. Two versions of the protocol are presented. The first protocol uses the Instantaneous Signal to Noise Ratio (ISNR) to activate the relay only when the corresponding instantaneous throughput is better than that of the direct link.

Free-Space Optical Communications

Journal of Lightwave Technology, 2006
With recent successes of laboratory, inatmosphere, and space demonstrations of free-space optical communications, there is no doubt that the technology is ready for operational deployment. While these successes have shown that there are no laws of physics against such systems, their estimated system costs are still much too high for serious ...

Free Space Optical Communications Link Budget Estimation

Lasers, Sources and Related Photonic Devices, 2010
This paper describes a new methodology of estimating the free space optical communications link budgets to be expected in conditions of severe turbulence. Comparisons will be given between theory and field measurements.
