Special Issue Information

Dear Colleagues,

Optical communication consists of optical wireless communications and fiber communications, both of which have the advantages of high bandwidth, low cost, and large transmission capacity. Therefore, it has a lot of commercial, military, and scientific applications. Specifically, optical wireless communications are considered to be one of the solutions to the next generation of wireless communication problems and they can meet growing communication needs. Recently, the focus of research has gradually expanded from point-to-point systems to multiple-input–multiple-output (MIMO) or networks. Therefore, our Special Issue, entitled "Optical Communication and Networking", has been established. This Special Issue aims to showcase cutting-edge research in the field of optical communication and networks. Both theoretical advancements and practical applications are welcome.

This Special Issue will cover a range of topics in the field, including (but not limited to) the following:

  • Free Space Optics (FSO), Visible Light Communications (VLC), Fiber Communications, and Underwater Optical Communications;
  • Optical MIMO Communications;
  • Routing algorithms and networks;
  • Mutiple access for optical terminals
  • Relay technique;
  • Adaptive optics on optical communications;
  • Orbital angular momentum (OAM);
  • Security optical communications;
  • Theoretical analysis or simulations, such as BER, channel capacity, outage probability, and throughput;
  • Prototype, experimental, and field trials;

In this paper, we present recent advancements in transmitter and receiver technologies for Optical Wireless Communication (OWC). OWC offers very wide license-free optical spectrum which enables very high capacity transmission. Additionally, beam-steered OWC is more power-efficient and more secure due to low divergence of light. One of the main challenges of OWC is wide angle transmission and reception because law of conservation of etendue restricts maximization of both aperture and field of view (FoV). On the transmitter side, we use Micro Electro-Mechanical System cantilevers activated by piezoelectric actuators together with silicon micro-lenses for narrow laser beam steering. Such design allowed us to experimentally demonstrate at least 10 Gbps transmission over 100° full angle FoV. On the receiver side, we show the use of photodiode array, and Indium-Phosphide Membrane on Silicon (IMOS) Photonic Integrated Circuit (PIC) with surface grating coupler (SGC) and array of SGC. We demonstrate FoV greater than 32° and 16 Gbps reception with photodiode array. PIC receiver allowed to receive 100 Gbps WDM with single SGC, and 10 Gbps with an array of SGC which had 8° FoV in the vertical angle and full FoV in the horizontal angle. Our results suggest that solutions presented here are scalable in throughputs and can be adopted for future indoor high-capacity OWC systems. Full article
