Nonlinear Optics and Optical Computing


Book Description

The conference "Nonlinear Optics and Optical Computing" was held May 11-19, 1988 in Erice, Sicily. This was the 13th conference organized by the International School of Quantum Electronics, under the auspices of the "Ettore Majorana" Center for Scientific Culture. This volume contains both the invited and contributed papers presented at the conference, providing tutorial background, the latest research results, and future directions for the devices, structures and architectures of optical computing. The invention of the transistor and the integrated circuit were followed by an explosion of application as ever faster and more complex microelectronics chips became available. The information revolution occa sioned by digital computers and optical communications is now reaching the limits of silicon semiconductor technology, but the demand for faster com putation is still accelerating. The fundamental limitations of information processing today derive from the performance and cost of three technical factors: speed, density, and software. Optical computation offers the potential for improvements in all three of these critical areas: Speed is provided by the transmission of impulses at optical veloc ities, without the delays caused by parasitic capacitance in the case of conventional electrical interconnects. Speed can also be achieved through the massive parallelism characteristic of many optical computing architec tures; Density can be provided in optical computers in two ways: by high spatial resolution, on the order of wavelengths of light, and by computa tion or interconnection in three dimensions.




Nonlinear Optical Materials and Devices for Applications in Information Technology


Book Description

Nonlinear Optical Materials and Devices for Applications in Information Technology takes the reader from fundamental interactions of laser light in materials to the latest developments of digital optical information processing. The book emphasises nonlinear optical interactions in bulk and low-dimensional semiconductors, liquid crystals and optical fibres. After establishing the basic laser--material interactions in these materials, it goes on to assess applications in soliton propagation, integrated optics, smart pixel arrays and digital optical computing.










Galileo Unbound


Book Description

Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes. This book tells the history of spaces of expanding dimension and increasing abstraction and how they continue today to give new insight into the physics of complex systems. Galileo published the first modern law of motion, the Law of Fall, that was ideal and simple, laying the foundation upon which Newton built the first theory of dynamics. Early in the twentieth century, geometry became the cause of motion rather than the result when Einstein envisioned the fabric of space-time warped by mass and energy, forcing light rays to bend past the Sun. Possibly more radical was Feynman's dilemma of quantum particles taking all paths at once — setting the stage for the modern fields of quantum field theory and quantum computing. Yet as concepts of motion have evolved, one thing has remained constant, the need to track ever more complex changes and to capture their essence, to find patterns in the chaos as we try to predict and control our world.




Optical Information Technology


Book Description

Research in optical information technology in Europe has been very active inrecent years. This volume records state-of-the-art research conducted in some 22 laboratories who have worked together within EC ESPRIT Basic Research Action 3199 up to 1992. The topics cover: (1) Active optical logic and switching devices - embracing new materials, nonlinear and electrooptic mechanisms as well as advanced device fabrication. These devices cover the range from all-optical nonlinear interferometer structures through hybrid optical-electronic modulators to integrated emitter-receiver structures. (2) The latest state of optical interconnect technology, embracing diffractive optics (binary and multi-level phase gratings), holographic space-variant elements and micro-refractive optics. (3) Contributions on optical information processing architecture and demonstrator projects. The materials base ranges from silicon to II-VI materials with the realisation of pn-junction devices in ZnSe. The research reported here lays the basis for long-term progress in devices for information processing.




Principles and Applications of Nonlinear Optical Materials


Book Description

Nonlinear optics is attracting attention because of its applications in telecommunications and its possibilities for optical computing. Optoelectronics has been singled out by many as being of considerable strategic importance. Optical fibre communications shows that optics is already a method of choice; nonlinear optics offers further improvements in efficiency and versatility.




Nonlinear Photonics


Book Description

Nonlinear photonics is the name given to the use of nonlinear optical devices for the generation, communication, processing, or analysis of information. This book is a progress report on research into practical applications of such devices. At present, modulation, switching, routing, decision-making, and detection in photonic systems are all done with electronics and linear optoelectronic devices. However, this may soon change, as nonlinear optical devices, e.g. picosecond samplers and switches, begin to complement optoelectonic devices. The authors succinctly summarize past accomplishments in this field and point to hopes for the future, making this an ideal book for newcomers or seasoned researchers wanting to design and perfect nonlinear optical devices and to identify applications in photonic systems.
