Available in PDF, EPUB and Kindle. Book excerpt: In this program, we have studied, experimentally and theoretically, the fundamental properties of photorefractive spatial solitons and the features of the interactions between and among them. We brought the topic of photorefractive solitons to the very front of soliton science and of nonlinear optics. In our work, we have put much emphasis on studying properties and features that are universal to all solitons in nature, even to those in fields that are very remote from optics. We have discovered a family of entirely new solitons: Incoherent Solitons, which can exist in any non-instantaneous nonlinear media in nature. We have shown that solitons interacting in full 3D media manifest particle properties (such as conservation of angular momentum) which a decade ago were thought to be absurd with respect to solitons. Finally, we have demonstrated the feasibility of a list of applications that are unique to photorefractive solitons, the most important ones being (1) nonlinear frequency conversion in soliton-induced waveguides, and (2) fixing 2D solitons into the crystalline lattice of the nonlinear medium: Integrated Optics in 3D. At the beginning of this program, there were not more than 3-4 additional groups in the US studying optical spatial solitons, and not more than 10 world wide. Today, much of it following our work, optical spatial solitons have become a platform for studies of all soliton phenomena, and have attracted more than 50 groups world wide. The best evidence for that in the number of participants in the last Conference on Nonlinear Guided Waves and Their Applications, which was doubled between from the 1996 and 1998 conferences to the 1999 conference.

This book was released on 2021-05-31 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights recent advances of optical spatial solitons in photorefractive materials ranging broadly from the coupling, modulation instability, effect of pyroelectricity, and the stability of photorefractive solitons, among other topics. Photorefractive solitons have been at the forefront of research because of their formation at low laser powers and unique saturable nonlinearity present in photorefractive materials which supports solitons in (2+1) D. There has been a spurt in research on photorefractive solitons recently, which has contributed to a greater understanding of the theoretical foundation of photorefractive solitons as also of their various interesting and practical applications. The book elucidates the diversity of photorefractive solitons and provides a good resource for students, researchers, and professionals in the area of nonlinear optics.

Download or read book Photorefractive Materials and Their Applications 1 written by Peter Günter and published by Springer. This book was released on 2006-04-09 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first volume of a set of three within the Springer Series in Optical Sciences, and is devoted to photorefractive effects, photorefractive materials, and their applications. Since the publication of our first two Springer books on Photorefractive Materials and Their Applications (Topics in Applied Physics, Vols. 61 and 62) almost 20 years ago, a lot of research has been done in this area. New and often expected effects have been discovered, theoretical models developed, known effects finally explained, and novel applications proposed. We believe that the field has now reached a high level of maturity, even if research continues in all areas mentioned above and with new discoveries arriving quite regularly. We therefore have decided to invite some of the top experts in the field to put together the state of the art in their respective fields. This after we had been encouraged to do so for more than ten years by the publisher, due to the fact that the former volumes were long out of print.

Available in PDF, EPUB and Kindle. Book excerpt: Light solitons in space spatial soliton) have been under an intensive theoretical and experimental research in the last three decades. The solitons evolve from nonlinear changes in the refractive index of the material, due to the light intensity distribution. When the modulation of the index confines the light beam in such a way that diffraction is compensated for exactly, the beam becomes self-trapped, and is called a spatial soliton. The nonlinear effects, which are responsible to soliton formation, are in general Kerr-like effects, causing local index changes proportional to the local light power. The index changes needed for spatial solitons require high power densities, and often exceed 1MWatt/sq.cm. We present here a new type of solitons in space, generated by the photorefractive (PR) effect in the medium. The solitonic waveform modulates the refractive index due to the PR effect, compensates for the diffraction exactly, and causes the light beam to propagate with no spatial change. This specific index modulation is introduced by interference gratings between the pairs of the spatial components (which compose the light beam), that are translated into phase gratings by the PR effect. Since the efficiency of this effect is independent of absolute light intensity, our solitons can be generated even at very moderate light power densities. Moreover, the same solitonic waveform can propagate unchanged in the medium, at very high or very low light intensities.

Landau Institute for Theoretical Physics, 2 Kosygin Str. , 117334 Moscow, Russia 2 Laboratoire de Physique, University of Bourgogne, 9 avenue A. Savary, 21078 Dijon, France After about a quarter of a century since the first theoretical predictions of op tical solitons, the industrial application of the optical soliton concept is near to reality in the booming field of modern telecommunications, where the de mand for high-speed data transmission and routing is of ever-growing. This book contains a set of lectures that were presented at a Les Houches school on optical solitons in September 1998. The school was successful in gathering among the lecturers most of the well-recognized world leaders in the field of optical solitons. A variety of different aspects of research into optical solitons was exposed in the lectures, ranging from the mathematical fundations of integrability theory to the rapidly evolving technological advances of fiber soliton-based telecommu nication systems. The overall impression that the participants and the students received from the school is that this field of research is an excellent example of the rapid transfer that occurs nowadays from basic science to the technological implementations of the first principles. The subjects that were covered by the lectures can be broadly grouped into four main categories: optical soliton the ory, fiber soliton telecommunications, optical soliton generation methods, and all-optical information processing via spatial solitons.
