“…The symbolic expressions in this table are given considering Scen 1 , for log-normal, single-side Gaussian, exponential, Maxwell, Gamma, Gamma-Gamma, Malaga, K, and generalized-K, as well as Scen 2 , for Gamma-exponential and exponential-Gamma channels. Finally, to obtain Cu , the formula provided in Table II-row 2 is exploited, in which, f γu (γ u ) is replaced by its expression in (20). Then, substituting the Meijer G expression of ln(1+χγ u ) [21, Eq.…”

<p>This paper derives symbolic models for end-to-end RIS-assisted FSO systems built on the fading model's probability density functions (PDFs) characterizing the sub-channels. We study some of the most popular models and derive closed-form expressions of PDFs, cumulative distributions, and moment-generating functions that are further exploited to analyze systems’ performance. By comparing scenarios in which the sub-channels are similar and different, we provide a clear understanding of how the overall RIS-assisted FSO channel behaves, along with comparative results based on commonly used models.</p>

“…Both types of the ORISes are typically on the scale of centimeters, making them less perceivable than the RF reflective intelligent surfaces. Figure 3 illustrates typical applications of the ORISes, including anti-blocking, beam splitting, beam switching and transmission diversity [12]. To fulfill these purposes, the 3D coordinates and rotation matrix of the ORISes and the receivers are estimated and fed back to the transmitter.…”

<p>Modern mobile communication systems exploit complicated modulations to increase spectrum efficiency and larger antenna arrays to suppress co-channel interferences. However, these techniques have also caused surges of power consumption and hardware cost, making it unsustainable to squeeze gains from the radio-frequency electronics. To circumvent the dilemma, optical mobile communication (OMC) systems exploit wideband lasers to carry data, and do not necessarily involve high-order modulation and oversized arrays. In OMC systems, parallel laser beams can achieve data rate of Tbps, connection density of thousands of links/m$^2$, and energy efficiency of Gbits/J, with low cost and low signal processing complexity, as long as the challenges in receiver tracking, channel decorrelation and anti-blocking can be tackled. To this end, this work presents a new OMC system architecture and discusses enabling technologies of practical OMC systems. A prototype is built to verify the feasibility of several key concepts. It is shown that a practical OMC system requires collaboration of fast and accurate positioning systems, rapid laser steerers, optical reflective intelligent surfaces and decorrelation optics.</p>

“…Nonetheless, solving these problems for extended source and multi-RIS cases is yet to be addressed. Moreover, the multi-RIS scenario is recently considered only in a performance analysis study in a single-source singledetector setup to achieve spatial diversity in [99]. In addition, the distortive effect of a directed tuned beam into the power distribution of unintended receivers should be carefully studied and addressed in future works.…”

The heterogeneity of optical wireless networks (OWNs) has expanded over decades in terms of services, node densities, mobility requirements, bandwidth needs, responsiveness, and physical device profile. Consequently, incorporating dynamic reconfigurability into future OWNs can satisfy their diverse realm of objectives. Towards this end, we provide our vision for the potential gains of integrating tunable optical elements in OWNs reflected in energy consumption reduction, coverage customization, data transfer rate boosting, highly accommodating multiple access schemes, enhancing physical layer security, supporting simultaneous services, and interference reduction. Finally, we speculate a roadmap for future research directions in tunable optics aided OWNs and the associated challenges with their deployment and operation.INDEX TERMS Optical wireless communications (OWC), smart optics, reconfigurable intelligent surfaces, intelligent reflecting surfaces.
