Free Download Antonina Malinina, "Optical Characteristics of Gas-Discharge Plasma in Mixtures of Mercury Dibromide Vapor with Gases"
English | ISBN: 1527544818 | 2020 | 205 pages | PDF | 3 MB
This volume presents the results of a number of studies on the spectral, integral and temporal characteristics of radiation and DBD plasma parameters on mixtures of mercury dibromide vapor and gases such as helium, argon, neon, xenon, krypton, nitrogen, and sulfur hexafluoride. Gas-discharge plasma in such mixtures is used as a working medium for exciplex sources of pulsed-periodic coherent lasers and spontaneous radiation (excilamps) in a blue-green spectral region with a wavelength at a maximum intensity equal to 502 nm. Such radiation sources attract the attention of researchers due to the highly specific radiation power (a record for the visible spectral range), the possibility of a wide tuning of the radiation wavelength, and the ability to operate in a repetitively pulsed mode. The book proposes the application of research results to create efficient gas-discharge excilamps of blue-green and ultraviolet spectral ranges, and will appeal to scientists, engineers and graduate students who specialize in plasma physics and quantum electronics.

Free Download Traffic Grooming in Optical WDM Mesh Networks by Keyao Zhu , Hongyue Zhu , Biswanath Mukherjee
English | PDF | 2005 | 189 Pages | ISBN : 0387254323 | 11 MB
Optical networks based on wavelength-division multiplexing (WDM) tech nology offer the promise to satisfy the bandwidth requirements of the Inter net infrastructure, and provide a scalable solution to support the bandwidth needs of future applications in the local and wide areas. In a waveleng- routed network, an optical channel, referred to as a lightpath, is set up between two network nodes for communication. Using WDM technology, an optical fiber link can support multiple non-overlapping wavelength channels, each of which can be operated at the data rate of 10 Gbps or 40 Gbps today. On the other hand, only a fraction of customers are expected to have a need for such a high bandwidth. Due to the large cost of the optical backbone infrastruc ture and enormous WDM channel capacity, connection requests with diverse low-speed bandwidth requirements need to be efficiently groomed onto hi- capacity wavelength channels. This book investigates the optimized design, provisioning, and performance analysis of traffic-groomable WDM networks, and proposes and evaluates new WDM network architectures. Organization of the Book Significant amount of research effort has been devoted to traffic grooming in SONET/WDM ring networks since the current telecom networks are mainly deployed in the form of ring topologies or interconnected rings. As the long-haul backbone networks are evolving to irregular mesh topologies, traffic grooming in optical WDM mesh networks becomes an extremely important and practical research topic for both industry and academia.

Free Download Optical Polymer Waveguides: From the Design to the Final 3D-Opto Mechatronic Integrated Device by Jörg Franke, Ludger Overmeyer, Norbert Lindlein, Karlheinz Bock, Stefan Kaierle, Oliver Suttmann, Klaus-Jürgen Wolter
English | EPUB | 2022 | 283 Pages | ISBN : 3030928535 | 106.6 MB
Light signals in optical waveguides can be used to transmit very large amounts of data quickly and largely without interference. In the industrial and infrastructural sectors, e.g. in the automotive and aerospace industries, the demand to further exploit this potential is therefore increasing. Which technologies can be used to effectively integrate systems that transmit data by means of light into existing components? This is a central question for current research. So far, there have been some technical limitations in this regard. For example, it is difficult to couple the signal of an optical waveguide to other optical waveguides without interruption. There is also a lack of suitable fabrication technologies for three-dimensional waveguides, as well as design and simulation environments for 3D opto-MID. This book addresses these and other challenges.
