During the past several decades, tremendous progress has been made in terahertz (THz) science and technology. There is a continuing need to have terahertz waves ready for practical applications. Terahertz photonic and electronic devices are being readied to be employed in application systems such as communication links, satellite communications, radar, surveillance, hard/soft material heating, biomedical treatment, and biomedical diagnostics. This book focuses on the advances in terahertz source technologies both from photonics and electronics (solid-state and vacuum-state) points of view. Written in a noncomplicated language, the book will be useful for a broad spectrum of readers, including advanced undergraduate- and graduate-level students in electronics and photonics, researchers in various disciplines in physics, chemistry, biology, astronomy, and electrical engineering, system engineers in various industrial sectors, general readers, and those who are interested in the interaction between electromagnetic waves and matters and in the effects of electromagnetic waves on matters.

This book is organized into three distinct parts, each focusing on specific applications and breakthroughs of THz sources within their respective domains: Photonics, Solid-State Electronics, and Vacuum Electronics.

Part I: Photonics
In the realm of Photonics, we shine a light on the limitless possibilities of THz technology. Here, we discover how the precision and control of lasers, optical parametric oscillators, and nonlinear optical processes have opened up new horizons. From medical imaging to security screening, the chapters in this section illuminate the vast array of applications where THz radiation is making a transformative impact.

Part II: Solid-State Electronics
Part II explores the world of Solid-State Electronics, where semiconductor electronic devices and novel materials are revolutionizing the THz landscape. Transistor circuits, semiconductor diodes, and plasmonic structures take center stage, driving advancements in imaging, spectroscopy, and communication. This section showcases how solid-state principles are transforming THz sources into compact, efficient, and versatile tools for a wide range of applications.

Part III: Vacuum Electronics
The final section, Vacuum Electronics, delves into the high-power domain of THz generation. Vacuum tubes, traveling wave tubes, gyrotrons, and other vacuum-based devices emerge as the powerhouses of the THz spectrum. From scientific research to industrial processes, this part highlights the pivotal role that vacuum electronics play in applications demanding high THz power levels, such as materials processing and plasma diagnostics.
