Structured Light for Optical Communication highlights principles and applications in the rapidly evolving field of structured light in wide-ranging contexts, from classical forms of communication to new frontiers of quantum communication. Besides the basic principles and applications, the book covers the background of structured light in its most common forms, as well as state-of-the-art developments. Structured light has been hailed as affording outstanding prospects for the realization of high bandwidth communication, enhanced tools for more highly secure cryptography, and exciting opportunities for providing a reliable platform for quantum computing. This book is a valuable resource for graduate students and other active researchers, as well as others who may be interested in learning about this cutting-edge research field.

Recent developments in the angular momentum of light present fresh challenges to long established concepts and pave the way for new and wide-ranging applications. The scope for structured light such as optical vortices, in particular, now extends from microfluidics to quantum information. This is the first comprehensive edited collection dealing with light carrying spin and orbital angular momentum, covering both fundamental and applied aspects. Written by internationally leading specialists, the chapters have been compiled to reflect the latest scientific progress and to address the multitude of theoretical, experimental and technical issues associated with this vibrant and exciting field. The volume is an authoritative reference for academic researchers and graduate students engaged in theoretical or experimental study of optical angular momentum and its applications. It will also benefit professionals in physics, optics and optical engineering, chemistry and biology.

Anthropology of Law in Muslim Sudan analyses the hybridity of law systems and the plurality of legal practices in rural and urban contexts of contemporary Sudan, shedding light on the complex relation between Islam and society. It is the outcome of the international research program ANDROMAQUE (Anthropologie du Droit dans les Mondes Musulmans Africains et Asiatiques), funded by the French ANR (Agence National de la Recherche) between 2011 and 2014. Crossing two disciplinary perspectives, anthropology and law, the present volume contains original fieldwork data on contemporary urban and rural Sudan. Focusing on two major domains, land property and courts, several case studies demonstrate the relevance of an approach based on "legal practices" to underline, first, the plurality and hybridity of law systems and the relative role of the Islamic reference in Sudanese society, and, secondly, the reshaping of legal behaviors and norms after the breaking point of South Sudan's independence in 2011.
