NEW TRENDS IN OPTICAL SOLITON TRANSMISSION SYSTEMS SOLID-STATE SCIENCE AND TECHNOLOGY LIBRARY Volume 5 Editorial Advisory Board L. R. Carley, Carnegie Mellon University, Pittsburgh, USA G. Declerck, IMEC, Leuven, Belgium F. M. Klaassen, University o/Technology, Eindhoven, The Netherlands Aims and Scope of the Series The aim of this series is to present monographs on semiconductor materials processing and device technology, discussing theory formation and experimental characterization of solid state devices in relation to their application in electronic systems, their manufacturing, their reliability, and their limitations (fundamental or technology dependent). This area is highly interdisciplinary and embraces the cross-section of physics of condensed matter, materials science and electrical engineering. Undisputedly during the second half of this century world society is rapidly changing owing to the revolutionary impact of new solid-state based concepts. Underlying this spectacular product development is a steady progress in solid-state electronics, an area of applied physics exploiting basic physical concepts established during the fIrst half of this century. Since their invention, transistors of various types and their corresponding integrated circuits (lCs) have been widely exploited covering progress in such areas as microminiaturization, megabit complexity, gigabit speed, accurate data conversion and/or high power applications. In addition, a growing number of devices are being developed exploiting the interaction between electrons and radiation, heat, pressure, etc., preferably by merging with ICs. Possible themes are (sub)micron structures and nanostructures (applying thin layers, multi layers and multi-dimensional confIgurations); micro-optic and micro-(electro)mechanical devices; high-temperature superconducting devices; high-speed and high-frequency electronic devices; sensors and actuators; and integrated opto-electronic devices (glass-fIbre communications, optical recording and storage, flat-panel displays). The texts will be of a level suitable for graduate students, researchers in the above fIelds, practitioners, engineers, consultants, etc., with an emphasis on readability, clarity, relevance and applicability. The titles published in this series are listed at the end of this volume.

As a result of worldwide demand for ultra high bitrate transmissions and increased scientific interest from the soliton community, research on optical solitons in fibres has made remarkable progress in recent years. In view of these trends, the Research Group for Optical Soliton Communications (ROSC), chaired by Akira Hasegawa, was established in Japan in April 1995 to promote collaboration and information exchange among communication service companies, industries and academic circles in the theory and application of optical solitons. This symposium was organized as a part of the ROSC activities. As with the 1 ROSC symposium, this symposium attracted enthusiastic response st from worldwide researchers involved in the subject of soliton based communications and intensive discussions were held throughout the symposium. Particular emphases were made to dispersion managements of soliton transmission. I would like to note that in the }'t symposium the (adiabatic) dispersion managements just began to appear in reducing radiation at amplifiers and reducing collision effects in WDM system. These have become standard this time, but in addition new, non-adiabatic dispersion managements have been introduced independently by various scientists all over the world. Nick Doran wanted to enhance soliton power to increase the SIN ratio in the low average dispersion systems, Georges wanted to reduce soliton power in standard fibre, Jacob and Carter wanted to send soliton in NRZ fibre, and Kumar and Hasegawa wanted to produce stationary chirped soliton. Ironically all these attempts have come up with essentially the same answer; change dispersion periodically. The non-adiabatic dispersion managements have created new nonlinear stable pulse with frequency chirp which has yet to be named. But this new pulse remarkably has solved practically all the classic problems of ideal solitons, the Gordon-Haus effect, collision induced frequency shift in wavelength division multiplexing (WDM) and interaction of adjacent solitons. Richardson's naming of it as "power soliton" is quite appropriate; the power soliton can propagate in standard fibre, allows WDM, allows dense packing and increases bit-rate per channel and reduces the Gordon-Haus effect because of zero average dispersion without sacrificing the SIN ratio etc .. The final day of the symposium was devoted to the introduction of the consortia of soliton based communications, MIDAS, ESTHER, UPGRADE, AON and STAR which are producing very interesting and fruitful results all over the world. In the preparation of the final draft of the proceedings, Messrs. H. Takehara and M. Shinomiya have again devoted a significant amount of their time to make the vii viii manuscript consistent and well coordinated. On behalf of ROSC, the editor would like to thank those efforts without which the publication of the book would have faced significant delay. The editor would also like to express his appreciation for the support of the Support Center for Advanced Telecommunications Technology Research Foundation (SCAT) to which Messrs. Takehara and Shinomiya are affiliated, which has enabled us to hold this successful symposium.
