This book presents posits a solution to the current limitations in global connectivity by introducing a global laser/optical communication system using constellation satellites, UAVs, HAPs and Balloons. The author outlines how this will help to satisfy the tremendous increasing demand for data exchange and information between end-users worldwide including in remote locations. The book provides both fundamentals and the advanced technology development in establishing worldwide communication and global connectivity using, (I) All-Optical technology, and (ii) Laser/Optical Communication Constellation Satellites (of different types, sizes and at different orbits), UAVs, HAPs (High Altitude Platforms) and Balloons. The book discusses step-by-step methods to develop a satellite backbone in order to interconnect a number of ground nodes clustered within a few SD-WAN (software-defined networking) in a wide area network (WAN) around the world in order to provide a fully-meshed communication network. This book pertains to anyone in optical communications, telecommunications, and system engineers, as well as technical managers in the aerospace industry and the graduate students, and researchers in academia and research laboratory. Proposed a solution to the limitations in global connectivity through a global laser/optical communication system using constellation satellites, UAVs, HAPs and Balloons; Provides both fundamentals and the advanced technology development in establishing global communication connectivity using optical technology and communication constellation satellites; Includes in-depth coverage of the basics of laser/optical communication constellation satellites.

The mid-infrared domain is a promising optical domain because it holds two transparency atmospheric windows, as well as the fingerprint of many chemical compounds. Quantum cascade lasers (QCLs) are one of the available sources in this domain and have already been proven useful for spectroscopic applications and free-space communications. This thesis demonstrates how to implement a private free-space communication relying on mid-infrared optical chaos and this requires an accurate cartography of non-linear phenomena in quantum cascade lasers. This private transmission is made possible by the chaos synchronization of two twin QCLs. Chaos in QCLs can be generated under optical injection or external optical feedback. Depending on the parameters of the optical feedback, QCLs can exhibit several non-linear phenomena in addition to chaos. Similarities exist between QCLs and laser diodes when the chaotic dropouts are synchronized with an external modulation, and this effect is known as the entrainment phenomenon. With a cross-polarization reinjection technique, QCLs can generate all-optical square-waves. Eventually, it is possible to trigger optical extreme events in QCLs with tilted optical feedback. All these experimental results allow a better understanding of the non-linear dynamics of QCLs and will extend the potential applications of this kind of semiconductor lasers.

This brief analyzes the characteristics of a microring resonator (MRR) to perform communication using ultra-short soliton pulses. The raising of nonlinear refractive indices, coupling coefficients and radius of the single microring resonator leads to decrease in input power and round trips wherein the bifurcation occurs. As a result, bifurcation or chaos behaviors are seen at lower input power of 44 W, where the nonlinear refractive index is n2=3.2×10−20 m2/W. Using a decimal convertor system, these ultra-short signals can be converted into quantum information. Results show that multi solitons with FWHM and FSR of 10 pm and 600 pm can be generated respectively. The multi optical soliton with FWHM and FSR of 325 pm and 880 nm can be incorporated with a time division multiple access (TDMA) system wherein the transportation of quantum information is performed.
