Special Issue Information

Dear Colleagues,

Optical communications are well known to support global communication networks due to their inherent characteristics in provisioning high-speed transmissions resulting from the utilization of different degrees of freedom of the photon. With the application of high-rate transmission in different scenarios, both terrestrial and underwater scenarios, and some revolutionary optical networks, such as elastic optical networks, underwater optical wireless networks, and optical wireless networks, have attracted intensive research interest. This Special issue aims to explore the issues in optical network design and optimization. It will focus on the state-of-the-art advances from fundamental theories, devices, and subsystems to networking applications, as well as future perspectives of optical networks. Topics of interest include but are not limited to the following areas:

  • Underwater optical wireless network design and optimization;
  • Elastic optical network design and optimization;
  • Underwater OWC sensor network design and optimization;
  • Hybrid communications and network design and optimization;
  • Optical materials, components, devices, and subsystems.

The purpose of this study is to increase the number of access users without having to install a new optical cable. With the proposed solution, the cost of installation work can be reduced and the number of users can be increased. Several parameters were observed to ensure that the modified network not only improved the scalability but also met the standard parameters. Among the parameters observed are the Q factor, bit error rate (BER), eye diagram and number of users. The study was continued using the spectrum conversion, slicing and duplication technique, where the signals would be duplicated in arrayed waveguide grating (AWG) and sliced using a demultiplexer WDM (WDM Demux). Simulations were performed using the latest-version Optisystem 18.0 software by setting the transmitter frequency value of 1491 nm, transmitter power of 0 dBm and loss of 0 dB. The result shows the total user access achieved is 196,608 users. Meanwhile, the common FTTH network is allowed 256 users only. The criterion is set based on the calculation of the Q factor, which is greater than 6, while the BER is less than 1 × 10−9. The Q factor for 196,608 users is 6.43617 and the BER is 4.52 × 10−11. The number of users is increased without compromising the quality of data offered to the customer. Our solution is the first reported to date. Full article

The growing demand for faster data transference and communication allowed the development of faster and more efficient communication network-based technologies, with wider bandwidth capability, high resilience to electromagnetic radiation, and low latency for information travelling. To provide a suitable alternative to satisfy data transmission and consumption demand, wireless systems were established after a decade of studies on this topic. More recently, visible light communication (VLC) processes were incorporated as interesting wireless approaches that make use of a wide frequency communication spectrum to reach higher bandwidth values and accelerate the speed of data/information transmission. For this aim, light converters, such as phosphor materials, are reported to efficiently convert blue light into green, yellow, and red emissions; however, long carrier lifetimes are achieved to enlarge the frequency bandwidth, thereby delaying the data transference rate. In this review, we focused on recent advances using different luminescent materials based on prominent polymers, organic molecules, and semiconductor nanocrystals with improved photophysical properties and favored carrier recombination dynamics, which are suitable to enhance the VLC process. Here, the main features of the above materials are highlighted, providing a perspective on the use of luminescent systems for efficient optical communication applications. Full article
