The feedforward linearization system of optical transmitter for Free space optical (FSO) link
2008 IEEE International RF and Microwave Conference, 2008Free-space optics (FSO) or Free-space photonics (FSP), is refers to the transmission of modulated visible or infrared (IR) beams through the atmosphere, which provides the wireless solution for the demand of high speed data rate and obtain broadband communications.

Proceedings of the 4th ACM Workshop on Wearable Systems and Applications, 2018
In near future, we expect the Virtual Reality (VR) headsets to be wireless and to be demanding data-rate up to Tbps, thus pushing RF technology to the limit. In this work, we explore the possibility of using steerable Free Space Optics (FSO) to create a wireless link between a wall-mounted static transceiver and a VR headset in motion with its user. We

A Throughput Model of TCP-FSO/ADFR for Free-Space Optical Satellite Communications
2019 IEEE Global Communications Conference (GLOBECOM), 2019We developed an analytic characterization of the steady-state throughput of a free-space optical satellite communications (FSOSC) system which includes an ultra-high-speed transmission control protocol for FSOSC (TCP-FSO) and an adaptive- distributed-frame-repetition (ADFR) technique.

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.

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.

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

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.

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.

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.
