Description

This book provides a thorough vision of the current trends in plasmonic optical fiber biochemical sensing. It gathers the most recent technological information and shows the maturity reached by the different subsequent technologies. Demonstrating roadmaps for the design process and implementation of plasmonic optical fiber biochemical sensors, the book bridges the gap between theory and application. With this philosophy, understanding key physical properties is of paramount importance for the efficient design of sensing platforms that will meet target specifications.

 

You will learn about the role of the fiber configuration and the functional coating on the properties of the resulting optrodes. You will also get an encompassing overview on all optical fiber configurations used for plasmonic sensing thus far, especially on the progress made over the last decade and rendering the technology compatible for use in real conditions. The book presents both fundamental aspects and advanced applications while focusing on recent and emerging fields of research, such as the use of tilted fiber Bragg gratings, the integration of sensors in situ, the use of smart interrogation techniques, and much more.

 

This is a unique reference for both beginners and experts in optical fiber-based sensors, especially for industrial engineers working in biophotonics and biochemical sensing, as it presents state-of-the-art design procedures and sensing features. The book’s theoretical background combined with recent advances of plasmonic-based optical fiber technologies also make it highly beneficial for all researchers, academics, and students specialized or interested in this flourishing and promising discipline.
