Special Issue Information

Dear Colleagues,

Free-space optical communication, characterized by high carrier frequency and a narrow transmission beam, is the preferred technology for achieving high-speed, long-distance, and secure information transmission. After more than 20 years of efforts by scientific researchers, laser communications have gone through the stages of theoretical research, technological breakthroughs, experimental verification, and engineering applications, and great achievements have been made. In recent years, with the introduction and establishment of new-generation information networks such as low-orbit satellite Internet and the integration of space, air, ground and sea, the demand for space optical communications has become increasingly urgent. Coupled with the rapid development of optoelectronics, measurement, control, and communication technologies, it is imperative to contemplate and research the next generation of free-space optical communication technology. To further advance the development of space optical communication, enhance academic exchange, and showcase the latest achievements in the next generation of free space optical communication systems, Photonics has decided to launch a Special Issue entitled "Next-Generation Free-Space Optical Communication Technology", which is now openly soliciting research papers and review articles in related fields and sincerely inviting experts and colleagues to contribute.

The scope of the call for papers includes:

  • New-generation space optical transmission networks, links and terminal architectures;
  • New generation of space optical beam pointing, acquisition and tracking technology;
  • New generation of space optical signal modulation, encoding and synchronization technology;
  • New generation of space optical information transmission, exchange and interconnection technology;
  • New generation of space optical time-frequency transmission, measurement and communication technology.

Smart cities like Neom require efficient and reliable transportation systems to support their vision of sustainable and interconnected urban environments. High-speed trains (HSTs) play a crucial role in connecting different areas of the city and facilitating seamless mobility. However, to ensure uninterrupted communication along the rail lines, advanced communication systems are essential to expand the coverage range of each base station (BS) while reducing the handover frequency. This paper presents the dual transceiver free space optical (FSO) communication system as a solution to achieve these objectives in the operational environment of HSTs in Neom city. Our channel model incorporates log-normal (LN) and gamma–gamma (GG) distributions to represent channel impairments and atmospheric turbulence in the city. Furthermore, we integrated the siding loop model, providing valuable insights into the system in real-world scenarios. To assess the system’s performance, we formulated the received signal-to-noise ratio (SNR) of the network under assumed fading conditions. Additionally, we analyzed the system’s bit error rate (BER) analytically and through Monte Carlo simulation. A comparative analysis with reconfigurable intelligent surfaces (RIS) and relay-assisted FSO communications shows the superior coverage area and efficiency of the dual transceiver model. A significant reduction of up to 76% and 99% in the number of required BSs compared to RIS and relay, respectively, is observed. This reduction leads to fewer handovers and lower capital expenditure (CAPEX) costs. Full article
