High-speed visible light communications (VLC) has been identified at an essential part of communication technology for 5G network. VLC offers the unique advantages of unregulated and secure channels, free of EM interference. Compared with the LED-based VLC transmitter, laser-based photonic systems are promising for compact, droop-free, and high-speed white lighting and VLC applications, ideal for ultra-fast 5G network and beyond. Besides the potential for achieving high data rate free-space communication links, i.e. the Li-Fi network, laser-based VLC technology can also enable underwater wireless optical communications (UWOC) for many important applications. In this paper, the recent research progress and highlights in the fields of laser-based VLC and UWOC have been reviewed with a focused discussion on the performance of various light sources, including the modulation characteristics of GaNbased edge emitting laser diodes (EELDs), superluminescent diodes (SLDs) and vertical-cavity surface-emitting lasers (VCSELs). Apart from the utilization of discrete components for building transceiver in VLC systems, the development of III-nitride laser-based photonic integration has been featured. Such on-chip integration offers many advantages, including having a small-footprint, high-speed, and low power consumption. Finally, we discuss the considerations of wavelength selection for various VLC and UWOC applications. Comparison of infrared (IR) and visible lasers for channels with high turbulence and the study of ultraviolet (UV) and visible lasers for non-line-of-sight (NLOS) communications are presented.Citation

Communication Through Breath Using Molecular Communication Modeling in Indoor Environments(2019-11) [Thesis]
Advisor: Alouini, Mohamed-Slim
Committee members: Alouini, Mohamed-Slim; Al-Naffouri, Tareq Y.; Amin, Osama; Dahrouj, HayssamThe concept of communication via breath is introduced under the molecular com munication system, where data can be exchanged through inhalation and exhalation. Those data are carried by volatile organic compounds (VOCs) or pathogens and transferred through an aerosol channel. In this thesis, we propose a molecular com munication model for an instantaneous source in a bounded indoor environment. The walls of this environment could be reflectors and/or absorbers by adjusting the value of deposition velocity. We assume a puff source in a given location and study the per formance of a point source since it is the basic element that can be used to derive the concentration of breath, cough, and sneezing, where the concentration of continuous source can be found by integrating a point source over space and time domains. Also, we show some numerical results to visualize the performance of these mathematical models and evaluate them. As a case study, we consider a real-life scenario of detecting a virus from an exhaled breath of a person standing in an indoor bounded room with reflective and absorptive walls. We derive the spatial-temporal concentration of an exhaled virus at the molecules source and the receiver in the room. Finally, we study the probability of misdetection using a suitable bio-sensor. -

20-meter underwater wireless optical communication link with 15 Gbps data rate(Optics Express, The Optical Society, 2016-10-24) [Article]The video streaming, data transmission, and remote control in underwater call for high speed (Gbps) communication link with a long channel length (∼10 meters). We present a compact and low power consumption underwater wireless optical communication (UWOC) system utilizing a 450-nm laser diode (LD) and a Si avalanche photodetector. With the LD operating at a driving current of 80 mA with an optical power of 51.3 mW, we demonstrated a high-speed UWOC link offering a data rate up to 2 Gbps over a 12-meter-long, and 1.5 Gbps over a record 20-meter-long underwater channel. The measured bit-error rate (BER) are 2.8 × 10-5, and 3.0 × 10-3, respectively, which pass well the forward error correction (FEC) criterion. © 2016 Optical Society of America.
