Terahertz Sources and Systems by R.E. Miles,P. Harrison,D. Lippens Pdf

Terahertz technology has moved on from being a useful but expensive circuit technique, applied largely in astronomy and space science, to become a subject in its own right, with important applications - terahertz imaging in particular. Indeed, the driving force in terahertz technology is currently imaging and spectroscopy. We now have the means to obtain images and chemical information in this frequency band. The images reproduced in this volume are striking and, not surprisingly, the clinical and analytical uses are the subject of intense activity. There is still, however, no complete range of active THz electronic components, but an encouraging conclusion of the book is that THz electronics will become necessary in communications systems in the foreseeable future. Terahertz technology has come of age, and the future lies open to new, exciting science and vital applications.

Highlights of Astronomy: Volume 14 by Karel van der Hucht Pdf

Recording the proceedings of the IAU XXVI General Assembly, this volume of the IAU Highlights of Astronomy covers virtually all aspects of modern astrophysics as discussed by 2400 participants from 73 countries. Notably, the common aspects of astrophysical phenomena known to exist in widely differing interstellar environments is thoroughly examined, providing fertile cross correlation from one specialisation to another. This text highlights the importance of the triennial IAU General Assemblies in bringing together the work of observers and theoreticians in widely different fields, but working towards a common goal: understanding the physics of the Universe. Together with the Proceedings of the IAU Symposia 235-240, this volume examines all of the astrophysics presented at the General Assembly.

Investigating Life in the Universe by Christopher K. Walker Pdf

This textbook gives a lively introduction to the search for extraterrestrial life. It is a guidebook to understanding the possibility of life elsewhere, pointing out landmarks and providing background information to facilitate further exploration of those areas of most interest to the reader. We are a planet of winners – winners of a cosmic lottery that has been in play since the universe began approximately 13.7 billion years ago. Our winnings include sentience and an underlying unease that has driven us to contemplate our place in the universe and the possibility of finding kindred spirits in the cosmos spreading out before us. To understand our origins and the possibility of life beyond Earth, we must look back and retrace the steps that have brought us to this point in space and time. In doing so, we will find the investigation of life to be a unifying theme in nature, requiring us to touch on all branches of the tree of knowledge. Using the Drake Equation as a theme, we begin with an overview of the topic and then go into the story of how we have acquired, or plan to acquire, the knowledge to solve it. As we make our journey, we will encounter some very interesting people – some you will likely know, while others may be new to you. Keep an open mind and allow this text to be your guide. Written in an engaging style, this textbook provides a foundational understanding of the rapidly advancing fields associated with the search for life in the universe. Each chapter includes illustrative figures and review questions for self-study. It will appeal to professionals, researchers, instructors, and undergraduate students, as well as anyone with an interest in astrophysics or astrobiology.

Spectroscopic Applications of Terahertz Quantum-Cascade Lasers by Tasmim Alam Pdf

Quantum cascade lasers (QCLs) are attractive for high-resolution spectroscopy because they can provide high power and a narrow linewidth. They are particularly promising in the terahertz (THz) range since they can be used as local oscillators for heterodyne detection as well as transmitters for direct detection. However, THz QCL-based technologies are still under development and are limited by the lack of frequency tunability as well as the frequency and output power stability for free-running operation. In this dissertation, frequency tuning and linewidth of THz QCLs are studied in detail by using rotational spectroscopic features of molecular species. In molecular spectroscopy, the Doppler eff ect broadens the spectral lines of molecules in the gas phase at thermal equilibrium. Saturated absorption spectroscopy has been performed that allows for sub-Doppler resolution of the spectral features. One possible application is QCL frequency stabilization based on the Lamb dip. Since the tunability of the emission frequency is an essential requirement to use THz QCL for high-resolution spectroscopy, a new method has been developed that relies on near-infrared (NIR) optical excitation of the QCL rear-facet. A wide tuning range has been achieved by using this approach. The scheme is straightforward to implement, and the approach can be readily applied to a large class of THz QCLs. The frequency and output stability of the local oscillator has a direct impact on the performance and consistency of the heterodyne spectroscopy. A technique has been developed for a simultaneous stabilization of the frequency and output power by taking advantage of the frequency and power regulation by NIR excitation. The results presented in this thesis will enable the routine use of THz QCLs for spectroscopic applications in the near future.

Sensing with Terahertz Radiation by Daniel Mittleman Pdf

The purpose of this book is two-fold. First, the various different methods of accessing the THz range are discussed, with a view to convince the reader that there have been qualitative and significant improvements over older, more conventional techniques. The text makes it clear that these improvements enable practical "real-world" applications of THz technology, in a manner which would not have been possible before. Second, the demonstrations and feasibility tests described serve as compelling evidence of the utility of such devices. Due to the unique characteristics of THz radiation and its interaction with materials, these devices have substantial advantages over other competing technologies in a number of different areas.

Quantum Nano-Photonics by Baldassare Di Bartolo,Luciano Silvestri,Maura Cesaria,John Collins Pdf

This book brings together more closely researchers working in the two fields of quantum optics and nano-optics and provides a general overview of the main topics of interest in applied and fundamental research. The contributions cover, for example, single-photon emitters and emitters of entangled photon pairs based on epitaxially grown semiconductor quantum dots, nitrogen vacancy centers in diamond as single-photon emitters, coupled quantum bits based on trapped ions, integrated waveguide superconducting nanowire single-photon detectors, quantum nano-plasmonics, nanosensing, quantum aspects of biophotonics and quantum metamaterials. The articles span the bridge from pedagogical introductions on the fundamental principles to the current state-of-the-art, and are authored by pioneers and leaders in the field. Numerical simulations are presented as a powerful tool to gain insight into the physical behavior of nanophotonic systems and provide a critical complement to experimental investigations and design of devices.
