Optical interference on free-space optical transceivers

Frontiers in Optics, 2003
We investigate the effects of optical interference on the performance of free-space optical (FSO) network links. Experiments indicate that interfering laser pulses of varying peak power, wavelength, and repetition rate incident upon FSO transceivers can produce up to a 90% reduction of average network throughput.

Analysing the Effect of Scintillation on Free Space Optics Using Different Scintillation Models

SPIN, 2019
Free space optics has gained a lot of popularity within a few spans of years. Although the concept of communication using modulated optical signals is not new, it did not come in existence practically due to the popular traditional wireless RF ...

Bit‐parallel, free‐space, optical communication

Communications on Pure and Applied Mathematics, 1995
AbstractIn this paper, we examine several issues of bit‐parallel free space optical communication such as arbitration operations, fault tolerance, and connector alignment. © 1996 John Wiley & Sons, Inc.

Miniaturization of free space optical systems

Applied Optics, 2010
Coherent illumination enables not only integrated optics, but also miniaturized free-space optics that takes advantage of the amplitude and phase control afforded by optical microelectromechanical systems (MEMS) and photonic crystals. These technologies also provide a practical and cost-effective means for integration and packaging of optical systems ...
