This book was released on 2018-07-13 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2017 in the subject Physics - Technical Physics, grade: 82, Charles Darwin University (School of Engineering and Information Technology), course: Electrical and Electronics Engineering, language: English, abstract: The focus is given on millimeter/micro wave signal generation based on external modulators. The working principle and modulation characteristics of Mach-Zehnder modulators (MZM) are introduced. Literature review is presented on generating millimeter/micro wave signals with 4-, 6-, and 8-times frequency multiplication based on cascaded MZMs or dual-parallel MZMs (DPMZMs). A novel scheme to optically generate a microwave signal with 10-times frequency multiplication is proposed. The proposed scheme is based on two DPMZMs and a polarizer. It does not require electrical phase shifters with specified degrees, which are needed in the conventional 10 times frequency multiplication structure. Simulation is conducted to evaluate the performance of the proposed scheme. When a 1 GHz RF drive signal turns into two DPMZMs with a 35 dB extinction ratio, the proposed 10 times frequency multiplier with an optical sideband suppression ratio (OSSR) higher than 25 dB can be obtained. A 10 GHz mm-wave with an RF spurious suppression ratio (RFSSR) over 16 dB is generated. A frequency quadrupling scheme based on a DPMZM is experimentally demonstrated. With a 3 GHz RF drive signal, an OSSR higher than 8 dB is obtained and a 12 GHz mm-wave is generated with an RFSSR over 11 dB.

This book was released on 2013-08-31 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theory of the linear and, especially, nonlinear electromagnetic response of graphene is presented. It is shown that, because of the massless energy spectrum of quasi-particles – electrons and holes – graphene has strongly nonlinear electromagnetic properties. Nonlinear electrodynamic phenomena – such as higher harmonic generation, frequency mixing and multiplication, detection – can be observed in graphene at electric fields several orders of magnitude lower than in many other nonlinear materials. A brief overview of experimental results is given. Prospects of future theoretical and experimental studies are discussed.

The introductory section of this book focuses on existing technologies for radio frequency and infrared sensing in biomedical applications, and their limited use in sensing applications, as well as the advantages of using THz technology in this context. This is followed by a detailed comparative analysis of THz electronics technology and other conventional electro optic THz setups highlighting the superior efficiency, affordability and portability of electronics-based THz systems. The book also discusses electronic sub-THz measurement systems for different biomedical applications. The chapters elucidate two major applications where sub-THz provides an edge over existing state of the art techniques used for non-invasive measurement of blood glucose levels and intraoperative assessment of tumor margins. There is a detailed articulation of an application of leveraging machine learning for measurement systems for non-invasive glucose concentration measurement. This helps the reader relate to the output in a more user-friendly format and understand the possible use cases in a more lucid manner. The book is intended to help the reader learn how to build tissue phantoms and characterize them at sub-THz frequencies in order to test the measurement systems. Towards the end of the book, a brief introduction to system automation for biomedical imaging is provided as well for quick analysis of the data. The book will empower the reader to understand and appreciate the immense possibilities of using electronic THz systems in the biomedical field, creating gateways for fueling further research in this area.​

Download or read book Femtosecond Optical Frequency Comb Principle Operation and Applications written by Jun Ye and published by Springer Science & Business Media. This book was released on 2006-06-15 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years, there has been a convergence between the fields of ultrafast science, nonlinear optics, optical frequency metrology, and precision laser spectroscopy. These fields have been developing largely independently since the birth of the laser, reaching remarkable levels of performance. On the ultrafast frontier, pulses of only a few cycles long have been produced, while in optical spectroscopy, the precision and resolution have reached one part in Although these two achievements appear to be completely disconnected, advances in nonlinear optics provided the essential link between them. The resulting convergence has enabled unprecedented advances in the control of the electric field of the pulses produced by femtosecond mode-locked lasers. The corresponding spectrum consists of a comb of sharp spectral lines with well-defined frequencies. These new techniques and capabilities are generally known as “femtosecond comb technology. ” They have had dramatic impact on the diverse fields of precision measurement and extreme nonlinear optical physics. The historical background for these developments is provided in the Foreword by two of the pioneers of laser spectroscopy, John Hall and Theodor Hänsch. Indeed the developments described in this book were foreshadowed by Hänsch’s early work in the 1970s when he used picosecond pulses to demonstrate the connection between the time and frequency domains in laser spectroscopy. This work complemented the advances in precision laser stabilization developed by Hall.

Download or read book Photonic Crystals written by John D. Joannopoulos and published by Princeton University Press. This book was released on 2011-10-30 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since it was first published in 1995, Photonic Crystals has remained the definitive text for both undergraduates and researchers on photonic band-gap materials and their use in controlling the propagation of light. This newly expanded and revised edition covers the latest developments in the field, providing the most up-to-date, concise, and comprehensive book available on these novel materials and their applications. Starting from Maxwell's equations and Fourier analysis, the authors develop the theoretical tools of photonics using principles of linear algebra and symmetry, emphasizing analogies with traditional solid-state physics and quantum theory. They then investigate the unique phenomena that take place within photonic crystals at defect sites and surfaces, from one to three dimensions. This new edition includes entirely new chapters describing important hybrid structures that use band gaps or periodicity only in some directions: periodic waveguides, photonic-crystal slabs, and photonic-crystal fibers. The authors demonstrate how the capabilities of photonic crystals to localize light can be put to work in devices such as filters and splitters. A new appendix provides an overview of computational methods for electromagnetism. Existing chapters have been considerably updated and expanded to include many new three-dimensional photonic crystals, an extensive tutorial on device design using temporal coupled-mode theory, discussions of diffraction and refraction at crystal interfaces, and more. Richly illustrated and accessibly written, Photonic Crystals is an indispensable resource for students and researchers. Extensively revised and expanded Features improved graphics throughout Includes new chapters on photonic-crystal fibers and combined index-and band-gap-guiding Provides an introduction to coupled-mode theory as a powerful tool for device design Covers many new topics, including omnidirectional reflection, anomalous refraction and diffraction, computational photonics, and much more.
