Special Issue Information

Dear Colleagues,

Optical communications, including both optical fiber communication and optical wireless communication, are essential in next-generation telecommunication systems. These technologies utilize light for transmitting data, providing unrivaled bandwidth and minimal latency, thus meeting the growing demand for data-heavy applications and services. As transmission speeds increase and reliability becomes increasingly critical, the significance of communication theory and information theory in optical communications has been increasing over the years. In today’s information era, optical communications and optical networks are essential technologies, providing unparalleled communication capacity and cost-effective connectivity to support bandwidth-demanding applications such as ultra-broadband access, cloud computing, and content sharing and storage. However, optical wireless communication and optical wireless network systems are currently short-distance systems and have no reliable mobility support; thus, the next-generation OWCs should provide a solution that focuses on vehicular applications, considering high data rates and long-range optical wireless communications and optical wireless networks.

This Special Issue, titled “Advances in Optical Communications and Optical Networks”, will welcome basic, methodological, and applied cutting-edge research contributions on the following topics:

  • Fundamental limits of optical communications;
  • Access, metro, and core optical network architectures;
  • DSP algorithms for quantum communications;
  • Optical network management and automation;
  • Channel modelling for optical wireless communication;
  • Laser communications for terrestrial/space networks;
  • Energy efficiency, resilience, and security of optical networks;
  • Communication aspects of novel fibers;
  • Optical network resource allocation schemes and algorithms;
  • High-speed forward error correction;
  • Joint optical communication and sensing;
  • Underwater optical communications or ultraviolet communications;
  • Next-generation OWC system;
  • Apply Deep learning for OWC systems.

Radio frequency (RF)-based wireless systems are broadly used in communication systems such as mobile networks, satellite links, and monitoring applications. These systems offer outstanding advantages over wired systems, particularly in terms of ease of installation. However, researchers are looking for safer alternatives as a result of worries about possible health problems connected to high-frequency radiofrequency transmission. Using the visible light spectrum is one promising approach; three cutting-edge technologies are emerging in this regard: Optical Camera Communication (OCC), Light Fidelity (Li-Fi), and Visible Light Communication (VLC). In this paper, we propose a Multiple-Input Multiple-Output (MIMO) modulation technology for Internet of Things (IoT) applications, utilizing an LED array and time-domain on-off keying (OOK). The proposed system is compatible with both rolling shutter and global shutter cameras, including commercially available models such as CCTV, webcams, and smart cameras, commonly deployed in buildings and industrial environments. Despite the compact size of the LED array, we demonstrate that, by optimizing parameters such as exposure time, camera focal length, and channel coding, our system can achieve up to 20 communication links over a 20 m distance with low bit error rate.
