Polarization Measurement and Control in Optical Fiber Communication and Sensor Systems A practical handbook covering polarization measurement and control in optical communication and sensor systems In Polarization Measurement and Control in Optical Fiber Communication and Sensor Systems, the authors deliver a comprehensive exploration of polarization related phenomena, as well as the methodologies, techniques, and devices used to eliminate, mitigate, or compensate for polarization related problems and impairments. The book also discusses polarization-related parameter measurement and characterization technologies in optical fibers and fiber optic devices and the utilization of polarization to solve problems or enable new capabilities in communications, sensing, and measurement systems. The authors provide a practical and hands-on treatment of the information that engineers, scientists, and graduate students must grasp to be successful in their everyday work. In addition to coverage of topics ranging from the use of polarization analysis to obtain instantaneous spectral information on light sources to the design of novel fiber optic gyroscopes for rotation sensing, Polarization Measurement and Control in Optical Fiber Communication and Sensor Systems offers: A thorough introduction to polarization in optical fiber studies, including a history of polarization in optical fiber communication and sensor systems Comprehensive discussions of the fundamentals of polarization, including the effects unique to optical fiber systems, as well as extensive coverage Jones and Mueller matrix calculus for polarization analysis In-depth treatments of active polarization controlling devices for optical fiber systems, including polarization controllers, scramblers, emulators, switches, and binary polarization state generators Fulsome explorations of passive polarization management devices, including polarizers, polarization beam splitters/displacers, wave-plates, Faraday rotators, and depolarizers Extensive review of polarization measurement techniques and devices, including time-division, amplitude-division, and wave-front division Stokes polarimeters, as well as various Mueller matrix polarimeters for PMD, PDL, and birefringence measurements Premiere of binary polarization state analyzers and binary Mueller matrix polarimeters pioneered by the authors, including their applications for highly sensitive PMD, PDL, and birefringence measurements Comprehensive discussion on distributed polarization analysis techniques developed by the authors, including their applications in solving real world problems Detailed descriptions of high accuracy polarimetric fiber optic electric current and magnetic field sensors Perfect for professional engineers, scientists, and graduate students studying fiber optics, Polarization Measurement and Control in Optical Fiber Communication and Sensor Systems enables one to quickly grasp extensive knowledge and latest development of polarization in optical fibers and will earn a place in the libraries of professors and teachers of photonics and related disciplines.

In this dissertation, the polarization-state control in coherent optical fiber communications is studied. A new automatic polarization-state control scheme called "polarization recombing" is proposed and experimentally verified. The system consists of a polarization beam splitter (a Wallaston prism), a 90° linear polarization rotator, and endless phase shifter, and a beam combiner. It features a very simple (probably the simplest) principle for polarization-state control and endlessness (resetting-free) in control is achieved. IN addition, in this scheme, the polarization-state of output light is always linear with a fixed inclination angle regardless of changes in the polarization-state of the incoming light. Such a characteristic is achieved without the aid of a polarimeter and is particularly useful in homodyne phase diversity receiver because a stable linearly polarized light is necessary for generating two lights having 90° phase difference. This feature has been demonstrated in simulated self-homodyne DPSK phase diversity receiver. It is fund that the scheme functions satisfactorily and the receiver sensitivity fluctuation is kept within 0.5 dB. at 200 Mbits/sec.

The growth of Internet traf?c in recent years surpassed the prediction of one decade ago. Data stream in individual countries already reached terabit/s level. To cope with the petabit class demands of traf?c in coming years the communication engineers are required to go beyond the incremental improvement of today’s technology. A most promising breakthrough would be the introduction of modulation f- mats enabling higher spectral ef?ciency than that of binary on–off keying scheme, virtually the global standard of ?ber-optic communication systems. In wireless communication systems, techniques of high spectral density modulation have been well developed, but the required techniques in optical frequency domain are much more complicated because of the heavier ?uctuation levels. Therefore the past trials of coherent optical modulation/detection schemes were not successful. However, the addition of high-speed digital signal processing technology is the fundam- tal difference between now and two decades ago, when trials of optical coherent communication systems were investigated very seriously. This approach of digital coherent technology has attracted keen interest among communication specialists, as indicated by the rapid increase in the pioneering presentations at the post-deadline sessions of major international conferences. For example, 32 terabit/s transmission in a ?ber experiment based on this technology was reported in post-deadline session of Optical Fiber Communication Conference (OFC) 2009. The advancement of the digital coherent technologies will inevitably affect the network architecture in terms of the network resource management for the new generation photonic networks, rather than will simply provide with huge transmission capacity.

Self-coherent receivers are promising candidates for reception of 100 Gbit/s data rates in optical networks. Self-coherent receivers consist of multiple optical delay interferometers (DI) with high-speed photodiodes attached to the outputs. By DSP of the photo currents it becomes possible to receive coherently modulated optical signals. Especially promising for 100 Gbit/s networks is the PolMUX DQPSK format, the self-coherent reception of which is described in detail.

The advantages of optical communications are many: ultra-high speed, highly reliable information transmission, and cost-effective modulation and transmission links to name but a few. It is no surprise that optical fiber communications systems are now in extensive use all over the world. Along with software and microelectronics, optical communication represents a key technology of modern telecommunication systems. Optical Communications: Components and Systems provides the basic material required for advanced study in theory and applications of optical fiber and space communication systems. After a review of some fundamental background material, component-based chapters discuss all relevant passive and active optical and optoelectronic components used in point-to-point links and in networks. Systems chapters address the analysis and optimization of both incoherent and coherent systems, introduce fiber optic link design, and discuss physical limits. The authors also provide an overview of applications such as optical networks and optical free-space communications. The advanced interactive multimedia communications of today and the future rely on optical fiber and space communication techniques. Optical Communications: Components and Systems offers engineers and physicists a working reference for the selection and design of optical communication systems and provides engineering students with a valuable text that prepares them for work in this essential and rapidly growing field.
