Available in PDF, EPUB and Kindle. Book excerpt: Organic lasers are broadly tunable coherent sources, potentially compact, convenient and manufactured at low-costs. Appeared in the mid 60’s as solid-state alternatives for liquid dye lasers, they recently gained a new dimension after the demonstration of organic semiconductor lasers in the 90's. More recently, new perspectives appeared at the nanoscale, with organic polariton and surface plasmon lasers. After a brief reminder to laser physics, a first chapter exposes what makes organic solid-state organic lasers specific. The laser architectures used in organic lasers are then reviewed, with a state-of-the-art review of the performances of devices with regard to output power, threshold, lifetime, beam quality etc. A survey of the recent trends in the field is given, highlighting the latest developments with a special focus on the challenges remaining for achieving direct electrical pumping of organic semiconductor lasers. A last chapter covers the applications of organic solid-state lasers.

Download or read book Optical Coherence Tomography Angiography of the Eye written by David Huang and published by Kugler Publications. This book was released on 2024-01-08 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical coherence tomography angiography (OCTA) has undergone tremendous growth since its first commercial introduction in 2014. Because it provides injection-free, capillary-resolution, 3-dimensional angiography of the retina and choroid, OCTA is likely to overtake fluorescein as the most important angiographic imaging technique in the eye. Nearly all manufacturers of ophthalmic OCT now offer OCTA products. A PubMed search now yields over 5700 articles on OCTA and related terms. Clinical investigators have already found a use for OCTA in almost every category of retinal and optic nerve diseases. This book is meant to bring together all this information so clinicians can have one authoritative text to turn to as we begin to use this new imaging modality that was never taught when we were in formal training.

Download or read book Guided Wave Nonlinear Optics written by D.B. Ostrowsky and published by Springer Science & Business Media. This book was released on 1992-04-30 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The object of this school, held at Cargese, Corsica (France) from August 12th to 24th 1991, was the presentation of the field of guided wave nonlinear optics in a comprehensive, coherent, and heuristic fashion. It seems appropriate that this school began with an historical introduction by Professor Nicolaas Bloembergen of Harvard, the acknowledged "father" of nonlinear optics, in general, and concluded with a round table discussion headed by Dr. Eric Spitz, the Scientific Director of a multinational electronics company interested in developing industrial applications of guided wave nonlinear optics. The lectures covered both the theoretical framework of the field and applications to basic scientific research, optical communications and technical instrumentation. Specific topics developed included materials for guided wave nonlinear optics, nonlinear interactions using integrated optical guides, nonlinear surface waves, solitons, fiber nonlinear optics, ultra-fast coupler switching as well as the related topic of fiber and integrated optical lasers and amplifiers. Lectures have also been devoted to squeezed states, chaos and strange attractors. The subjects covered by the school underlines one of the major ways in which this field has evolved over the past thirty some odd years. The path from the original experiments with materials requiring mega-watt power lasers to the recent developments in guided wave configurations using milliwatt power diode lasers is marked by the conjunction of ever improving fundamental scientific comprehension and continuing technological developments.

Download or read book Photonic Networks written by Giancarlo Prati and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: The day when fiber will deliver new, yet now only foreseeable, broadband ser vices to the end user is getting nearer and nearer as we make our way towards the prophetic year 2000. Step by step, as we move from first generation lasers and fibers to the by now common erbium-doped fiber amplifiers, looking forward to such things as wavelength multiplexing and solitons, photonic switching and optical storage, the community of researchers in optical communications has stepped into the era of photonic networks. It is not just a question of terminology. Optical communication means tech nology to the same extent that photonic network means services. If it is true that information is just as marketable a product as oil or coke, the providing of an extensive global information infrastructure may end up having an even greater impact than the setting up of a world-wide railroad network did at the beginning of the industrial era. Just like wagons, bandwidth will be responsible for carrying and delivering goods to customers. The challenge for all of us in this field is for it to function in every section of the overall network, transport, access and customer area, in the best possible way: the fastest, most economical and most flexible. New services provided by a new network that exploits the potential and peculiarities of photonics surely requires a rethinking of solutions, new ideas, new architec tures, new design, especially where electronics is still dominant, as in transport and access networks.
Download or read book Optical Fiber Telecommunications VII written by Alan Willner and published by Academic Press. This book was released on 2019-10-16 with total page 1118 pages. Available in PDF, EPUB and Kindle. Book excerpt: With optical fiber telecommunications firmly entrenched in the global information infrastructure, a key question for the future is how deeply will optical communications penetrate and complement other forms of communication (e.g., wireless access, on-premises networks, interconnects, and satellites). Optical Fiber Telecommunications, the seventh edition of the classic series that has chronicled the progress in the research and development of lightwave communications since 1979, examines present and future opportunities by presenting the latest advances on key topics such as: Fiber and 5G-wireless access networks Inter- and intra-data center communications Free-space and quantum communication links Another key issue is the use of advanced photonics manufacturing and electronic signal processing to lower the cost of services and increase the system performance. To address this, the book covers: Foundry and software capabilities for widespread user access to photonic integrated circuits Nano- and microphotonic components Advanced and nonconventional data modulation formats The traditional emphasis of achieving higher data rates and longer transmission distances are also addressed through chapters on space-division-multiplexing, undersea cable systems, and efficient reconfigurable networking. This book is intended as an ideal reference suitable for university and industry researchers, graduate students, optical systems implementers, network operators, managers, and investors. Quotes: "This book series, which owes much of its distinguished history to the late Drs. Kaminow and Li, describes hot and growing applied topics, which include long-distance and wideband systems, data centers, 5G, wireless networks, foundry production of photonic integrated circuits, quantum communications, and AI/deep-learning. These subjects will be highly beneficial for industrial R&D engineers, university teachers and students, and funding agents in the business sector." Prof. Kenichi Iga President (Retired), Tokyo Institute of Technology "With the passing of two luminaries, Ivan Kaminow and Tingye Li, I feared the loss of one of the premier reference books in the field. Happily, this new version comes to chronicle the current state-of-the-art and is written by the next generation of leaders. This is a must-have reference book for anyone working in or trying to understand the field of optical fiber communications technology." Dr. Donald B. Keck Vice President, Corning, Inc. (Retired) "This book is the seventh edition in the definitive series that was previously marshaled by the extraordinary Ivan Kaminow and Tingye Li, both sadly no longer with us. The series has charted the remarkable progress made in the field, and over a billion kilometers of optical fiber currently snake across the globe carrying ever-increasing Internet traffic. Anyone wondering about how we will cope with this incredible growth must read this book."

Download or read book Nanophotonic Devices for Linear and Nonlinear Optical Signal Processing written by Christian Koos and published by Karlsruher Institut Fur Technologie. This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: High index-contrast nanophotonic devices are key components for future board-to-board and chip-to-chip optical interconnects: The strong confinement of light enables dense integration, and nonlinear effects can be exploited at low power levels. Cheap large-scale production is possible by using highly parallel microfabrication techniques, and semiconductor-based nanophotonic devices can be integrated together with electronic circuitry on a common chip. Particularly intense research is carried out to realise optical devices on silicon substrates, using mature complementary metal-oxide-semiconductor (CMOS) fabrication techniques.This book discusses the modelling, fabrication and characterization of linear and nonlinear nanophotonic devices. Roughness-related scattering loss in high index-contrast waveguides is investigated both theoretically and experimentally, and methods of loss reduction are developed. Novel silicon-based devices for electro-optic modulation and for all-optical signal processing are presented. Nonlinear dynamics in active quantum-dot devices are studied, and resonant field enhancement is exploited to improve the efficiency of nonlinear interaction.
