Special Issue Information

Dear Colleagues,

The proliferation of sensor networks has transformed the way we collect and disseminate data in various domains, such as environmental monitoring, healthcare, industrial automation, and smart cities. Optical communication, with its intrinsic advantages in terms of high bandwidth, low latency, and energy efficiency, has emerged as a critical enabler for enhancing the performance, scalability, and reliability of sensor networks.

The scope of this Special Issue spans multiple aspects within optical communication in sensor networks, including but not limited to:

  • Optical sensor design: innovative optical sensor designs and architectures that enhance data acquisition capabilities, sensitivity, and precision.
  • Optical signal processing: techniques for processing and analyzing optical data in sensor networks.
  • Optical network topologies: studies on the design and optimization of optical network topologies for efficient data transmission and resource allocation.
  • Energy efficiency: research on minimizing power consumption in optical communication components and systems to extend sensor network lifetimes.
  • Security and reliability: the exploration of security measures and strategies to ensure the confidentiality, integrity, and availability of data transmitted through optical channels in sensor networks.
  • Applications: real-world applications of optical communication in sensor networks, ranging from environmental monitoring and precision agriculture to healthcare and smart infrastructure.

The use of analog radio-over-fiber (RoF) systems combined with power-over-fiber (PoF) systems has been proposed in recent years for applications involving remote sensors used in hazardous environments or where electrical wiring may be impractical. This article presents a hybrid architecture topology that combines PoF and RoF, using Raman amplification to obtain RF gain. The first emphasis is placed on the use of two types of high-power laser sources (HPLSs) for the PoF system: a 1480 nm Raman-based HPLS and a 1550 nm HPLS that is based on an erbium-doped fiber amplifier (EDFA). The second emphasis of this paper is on how these two HPLSs simulate Raman scattering (SRS) in the fiber, considering different lengths of SMF 28 for the link. Thus, a comparative analysis is proposed considering the effects induced on the RF signal, mainly focused on its RF power gain (GRF), noise figure (NF), and spurious-free dynamic range (SFDR). The obtained results show that the architecture using a PoF system based on the 1550 nm HPLS benefits from a lower noise figure degradation, even when the noise generated by the optical amplification is considered.
