Optical Bistability: Controlling Light with Light focuses on optical bistability in nonlinear optical systems. Emphasis is on passive (non-laser) systems that exhibit reversible bistability with input intensity as the hysteresis variable, along with the physics and the potential applications of such systems for nonlinear optical signal processing. This book consists of seven chapters and begins with a historical overview of optical bistability in lasers and passive systems. The next chapter describes steady-state theories of optical bistability, including the Bonifacio-Lugiato model, as well as the boundary conditions of an optical cavity and the coupled Maxwell-Bloch equations. Both intrinsic and hybrid experiments are then described, along with light-by-light control, pulse reshaping, and external switching. The transient phenomena that arise either from instabilities in the bistable systems themselves or from fluctuations in the number of nonlinear atoms or in the number of intracavity photons are also considered. The final chapter examines the characteristics and fundamental limitations of an ideal device, the prospect of improving devices by identifying giant nonlinearities, and the utilization of the full power of optics by parallel processing. This monograph is intended for new entrants and active workers in the field of optical bistability.
This book provides a comprehensive introduction to the theoretical and experimental studies of atomic optical bistability and multistability, and their dynamical properties in systems with two- and three-level inhomogeneously-broadened atoms inside an optical cavity. By making use of the modified linear absorption and dispersion, as well as the greatly enhanced nonlinearity in the three-level electromagnetically induced transparency system, the optical bistablity and efficient all-optical switching can be achieved at relatively low laser powers, which can be well controlled and manipulated. Until now, the rapid rate of progress in applications of multilevel systems in cross-disciplinary field has made it difficult to newcomers to the field to obtain a broad overview of this topic. This monograph will serve the purpose.
This is a collection of papers presented at the Topical Meeting on Optical BistabiJity (OB3) held December 2-4,1985 in Tucson, Arizona. The increase in attendance to almost 200 shows that interest continues to grow in the sub ject of optical bistability (OB) and its wider implications both in application to "optical digital computing" and to basic physics, notably instabilities and spatial effects. The maturing of the field is evidenced by the fact that the number of experimental papers has caught up with the number of theoretical ones. These trends were already apparent in OB2 and the 1984 Royal Society Meeting on Optical Bistabilty, Dynamical Nonlinearity and Photonic Logic. Progress in experiment.al topics included guided-wave OB, mostly ther mal, picol'econd switching, studies on quite a number of new materials, op tical computing, and pattern recognition using arrays of nonlinear etalons. Theoretical progress ranged from rather practical calculations on device per formance, noise effects on switching, and transverse and longitudinal spatial effects to fundamental studies of dynamics, instabilities, and chaos. The Conference also included both theoretical ideas on optical computer archit.ecture and intrinsic OB circuit elements such as as full adder as well as t.he first demonstration of an intrinsic optical circuit in the form of a cas cadable loop with bufferd st.ores. A first demostration of a simple pattern recognition algorithm using 2-D arrays of spots on a ZnSe int.erference filter was reported.
An in-depth exploration of the dynamics of lasers and other relevant optical systems for graduate students and researchers.
This book reflects the latest advances in nonlinear optics. Besides the simple, strict mathematical deduction, it also discusses the experimental verification and possible future applications, such as the all-optical switches. It consistently uses the practical unit system throughout. It employs simple physical images, such as "light waves" and "photons" to systematically explain the main principles of nonlinear optical effects. It uses the first-order nonlinear wave equation in frequency domain under the condition of “slowly varying amplitude approximation" and the classical model of the interaction between the light and electric dipole. At the same time, it also uses the rate equations based on the energy-level transition of particle systems excited by photons and the energy and momentum conservation principles to explain the nonlinear optical phenomenon. The book is intended for researchers, engineers and graduate students in the field of optics, optoelectronics, fiber communication, information technology and materials etc.
This volume presents selected papers from the 3rd International Conference on Optical and Wireless Technologies, conducted from 16th to 17th March, 2019. It focuses on extending the limits of currently used systems encompassing optical and wireless domains, and explores the latest developments in applications like photonics, high speed communication systems and networks, visible light communication, nano-photonics, wireless, and MIMO systems. The proceedings contain high quality scholarly articles, giving insight into the analytical, experimental, and developmental aspects of systems, techniques, and devices in these spheres. This volume will prove useful to researchers and professionals alike.
The meeting will provide an up-to-date, state-of-the-art exposition of results and techniques concerning theoretical and experimental studies of optical devices showing strong non-linear behaviour. Special attention will be paid towards the production of intense squeezed and sub-Poissionian light, formation of spatial patterns in laser systems, atomic dynamics in intense laser fields and the characterization of instabilities and chaotic dynamics in optical media.

A non-linear wave is one of the fundamental objects of nature. They are inherent to aerodynamics and hydrodynamics, solid state physics and plasma physics, optics and field theory, chemistry reaction kinetics and population dynamics, nuclear physics and gravity. All non-linear waves can be divided into two parts: dispersive waves and dissipative ones. The history of investigation of these waves has been lasting about two centuries. In 1834 J. S. Russell discovered the extraordinary type of waves without the dispersive broadening. In 1965 N. J. Zabusky and M. D. Kruskal found that the Korteweg-de Vries equation has solutions of the solitary wave form. This solitary wave demonstrates the particle-like properties, i. e. , stability under propagation and the elastic interaction under collision of the solitary waves. These waves were named solitons. In succeeding years there has been a great deal of progress in understanding of soliton nature. Now solitons have become the primary components in many important problems of nonlinear wave dynamics. It should be noted that non-linear optics is the field, where all soliton features are exhibited to a great extent. This book had been designed as the tutorial to the theory of non-linear waves in optics. The first version was projected as the book covering all the problems in this field, both analytical and numerical methods, and results as well. However, it became evident in the process of work that this was not a real task.
