Download or read book Pulse and Synchro Photon Electronics written by Ferdinandas Vaitiekūnas and published by Cambridge Scholars Publishing. This book was released on 2023-03-28 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the theory of large-signal nonlinear impulse processes occurring in bipolar and field-effect transistors with a Schottky gate, collapse TRAPATT and tunnel diodes, superlattices, and double heterojunction lasers. It evaluates the maximum speed of impulse operation of these elements and experimentally constructs the generation of pulse oscillations with a repetition frequency of up to 1, 2 and 4 GHz. Original or adapted methods of mathematical modeling of processes provide an opportunity to obtain quantitative dependencies of generated pulse parameters, while the book also details the synchro-photon effect. In addition, as shown here, when a semiconductor element is switched on by an electric pulse, and at the same time a pulse of photons synchronously illuminates it, an effect occurs which increases the switching speed of the element by an order of magnitude. At the same time, the switching transient characteristic is shortened by 10 times or more. After applying this effect in pulse generators in the gigahertz frequency range, an increase in the repetition frequency of the generated oscillations is possible.

Download or read book Optical and Electronic Process of Nano Matters written by Motoichi Ohtsu and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sizes of electronic and photonic devices are decreasing drastically in order to increase the degree of integration for large-capacity and ultrahigh speed signal transmission and information processing. This miniaturization must be rapidly progressed from now onward. For this progress, the sizes of materials for composing these devices will be also decreased to several nanometers. If such a nanometer-sized material is combined with the photons and/or some other fields, it can exhibit specific characters, which are considerably different from those ofbulky macroscopic systems. This combined system has been called as a mesoscopic system. The first purpose of this book is to study the physics of the mesoscopic system. For this study, it is essential to diagnose the characteristics of miniaturized devices and materials with the spatial resolution as high as several nanometers or even higher. Therefore, novel methods, e.g., scanning probe microscopy, should be developed for such the high-resolution diagnostics. The second purpose of this book is to explore the possibility of developing new methods for these diagnostics by utilizing local interaction between materials and electron, photon, atomic force, and so on. Conformation and structure of the materials of the mesoscopic system can be modified by enhancing the local interaction between the materials and electromagnetic field. This modification can suggest the possibility of novel nano-fabrication methods. The third purpose of this book is to explore the methods for such nano-fabrication.
Download or read book Laser Pulses written by Igor Peshko and published by BoD – Books on Demand. This book was released on 2012-10-17 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses aspects of laser pulses generation, characterization, and practical applications. Some new achievements in theory, experiments, and design are demonstrated. The introductive chapter shortly overviews the physical principles of pulsed lasers operation with pulse durations from seconds to yoctoseconds. A theory of mode-locking, based on the optical noise concept, is discussed. With this approximation, all paradoxes of ultrashort laser pulse formation have been explained. The book includes examples of very delicate laser operation in biomedical areas and extremely high power systems used for material processing and water purification. We hope this book will be useful for engineers and managers, for professors and students, and for those who are interested in laser science and technologies.

Download or read book Functional Imaging by Controlled Nonlinear Optical Phenomena written by Kazuyoshi Itoh and published by John Wiley & Sons. This book was released on 2013-09-03 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrafast lasers allow high-precision imaging and manipulation for biological and medical applications. Nonlinear optical microscopy has provided researchers with unique possibilities of three-dimensional imaging of biological cells and tissues. Nonlinear optical imaging technique is a rapidly emerging research area with widespread fundamental research and clinical applications. Nonlinear optical imaging allows both structural and functional imaging with cellular level resolution imaging in biological systems. The introduction of endogenous or exogenous probes can selectively enhance contrast for molecular targets in a living cell as well as supply functional information on processes. With the aim to control nonlinear optical processes and to obtain functional images, nonlinear optical processes can be controlled by photo-controlled probes and/or parameters of ultrafast laser pulses, such as time, space, polarization, and phase. This book gives an overview of the nonlinear optical process by ultrafast laser pulses and explains how the basics of nonlinear optical microscopy led to the most advanced techniques of photo-controlled nonlinear optical microscopy.

Download or read book Advanced Photon Counting written by Peter Kapusta and published by Springer. This book was released on 2015-04-23 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on Time-Correlated Single Photon Counting (TCSPC), a powerful tool allowing luminescence lifetime measurements to be made with high temporal resolution, even on single molecules. Combining spectrum and lifetime provides a “fingerprint” for identifying such molecules in the presence of a background. Used together with confocal detection, this permits single-molecule spectroscopy and microscopy in addition to ensemble measurements, opening up an enormous range of hot life science applications such as fluorescence lifetime imaging (FLIM) and measurement of Förster Resonant Energy Transfer (FRET) for the investigation of protein folding and interaction. Several technology-related chapters present both the basics and current state-of-the-art, in particular of TCSPC electronics, photon detectors and lasers. The remaining chapters cover a broad range of applications and methodologies for experiments and data analysis, including the life sciences, defect centers in diamonds, super-resolution microscopy, and optical tomography. The chapters detailing new options arising from the combination of classic TCSPC and fluorescence lifetime with methods based on intensity fluctuation represent a particularly unique highlight.
