Plasmonics stems from the surface charge density oscillations at metal–dielectric interface, leading to extremely strong light–matter interactions. In the past few decades, plasmonics has become one of the most favorite fields/techniques in realizing high-performance photonic devices. For this purpose, different new concepts, such as exploration of different radiation frequency regions, two-dimensional materials/heterostructures, and different types of substrates for the excitation of plasmons have been investigated for plasmonics-based sensors and detectors. This book focuses on the recent and advanced works on optical sensors and detectors utilizing plasmonic techniques for opto-electronic applications. The book is unique as it describes both sensors and detectors based on plasmonics and their practical applications in a single book, a feature not found in any book so far.

This book describes important recent developments in fiber optic sensor technology and examines established and emerging applications in a broad range of fields and markets, including power engineering, chemical engineering, bioengineering, biomedical engineering, and environmental monitoring. Particular attention is devoted to niche applications where fiber optic sensors are or soon will be able to compete with conventional approaches. Beyond novel methods for the sensing of traditional parameters such as strain, temperature, and pressure, a variety of new ideas and concepts are proposed and explored. The significance of the advent of extended infrared sensors is discussed, and individual chapters focus on sensing at THz frequencies and optical sensing based on photonic crystal structures. Another important topic is the resonances generated when using thin films in conjunction with optical fibers, and the enormous potential of sensors based on lossy mode resonances, surface plasmon resonances, and long-range surface exciton polaritons. Detailed attention is also paid to fiber Bragg grating sensors and multimode interference sensors. Each chapter is written by an acknowledged expert in the subject under discussion.
