A battery recharge model for WSNs using Free-Space Optics (FSO)
2008 IEEE International Multitopic Conference, 2008One of the most critical limiting factor for a Wireless Sensor Network (WSN) is its battery life. Therefore, a very desirable feature of WSN would be its rechargability to remain operational over longer period of times. However, the nodes needing recharge may not be accessible. In this paper, we present a battery recharge model in WSNs for inaccessible

2020 European Conference on Optical Communications (ECOC), 2020
We developed a novel full-duplex FSO transceiver with optical-image stabilizer (OIS) and free-space-optical circulator. The OIS technology, which is widely used by smartphones cameras, was successfully implemented to expand the transceiver field-of-view (FOV) and maintain laser beam alignment with efficient seamless coupling to fiber core.

Incremental adaptive networks implemented by free space optical (FSO) communication
2018The aim of this paper is to fully analyze the effects of free space optical (FSO) communication links on the estimation performance of the adaptive incremental networks. The FSO links in this paper are described with two turbulence models namely the Log-normal and Gamma-Gamma distributions. In order to investigate the impact of these models we produced

Fundamentals of Free-Space Optical (FSO) Communication System
2014Free-space optical (FSO) must be included in the set of solutions for meeting the bandwidth requirements of the modern internet. FSO communication is the most practical alternative to solve the bottleneck broadband connectivity problem, and as a supplement to conventional radio frequency (RF)/microwave links.

Modulating Retroreflector-based Free-space Optical (FSO) Communications
2014In this chapter, the niche area of free-space laser communications and data links which use modulating retroreflectors, or retro-modulators, will be discussed. This is a growing area of interest since technology can now support “shutters” that can achieve usable communications rates.

Weather Influence on Performance of a Seamless Free Space Optic (FSO) Link in a PON Scenario
2019 21st International Conference on Transparent Optical Networks (ICTON), 2019The upcoming 5G communications require for high bandwidth data rates that challenges the current fiber-wireless convergence based on Radio Frequency links. Free Space Optical (FSO) communications represents a valid alternative to meet the high data rate requirements.

Modulation, Detection, and Coding for Free-space Optical (FSO) Communications
2014The process of modulation consists of mapping the information onto magnetic medium (a carrier). There are mainly three parameters of the carrier which can be varied to perform the modulation process for mapping the information into changes in either the amplitude, phase, or frequency of the carrier.

Impact of Free-Space Optics (FSO) Switching in Quantum Datacentre Environments
Frontiers in Optics + Laser Science 2025 (FiO, LS)We evaluate FSO switches’ impact on the entanglement fidelity of a 9-node tree datacentre-like topology. Simulations show that each switch layer reduces fidelity by 8.9%, only partially mitigated by EPL distillation’s improvement of 5.61%.

Circular polarization and availability in free space optics (FSO) communication systems
2010 IEEE Latin-American Conference on Communications, 2010A great variety of atmospheric phenomena such as absorption, dispersion and turbulence can cause big variations in the attenuation of the beam of light of a laser. The absorption and the turbulence can be measured by means of a system free space optics (FSO) designed appropriately.

Mitigation Techniques for Improved Free-space Optical (FSO) Communications
2014Modern free-space optical (FSO) communications need to be robust and seamless, providing high bandwidth at the right quality of service to both communication terminals in presence of various atmospheric conditions. This means that FSO communications need to have improved reliability when operating in adverse atmospheric conditions.
