This book is written in such a way that it can supplement all necessary information of nanophotonic principles /processes, nanophotonic devices, nanostructured / nano-engineered optical fibers, nanostructured fiber-optic sensing systems, etc.; which are highly usable for various industries - starting from mechanical, solar / nuclear power to oil and biochemical or even under the sea as well as space applications through online measurements of various measurands like - temperature, pressure, strain, vibration, fluid flow, fluid level, rotation, acceleration, current, pH, humidity, UV /IR radiation, nuclear radiation, toxic gas and many more.

The book covers all latest developments of nanophotonic devices as well as nanostructured fiber-optic sensor systems. Moreover, all necessary nanophotonic processes of nanostructured fiber-optic sensor systems and components (e.g. nanostructured sensors / nanostructured light sources (i.e., LED, laser, display devices, etc.) / nano photodetectors, / nano switch / nano modulator / nano-optical fiber etc.) are discussed in a lucid manner, so that learners, i.e., UG / PG students (of nanotechnology, nanophotonics, nano-sensor systems, nanostructured fiber-optic sensor system, etc.) in different Photonic Engineering / Photonic Physics / Applied Physics) or relevant industrial technical experts find it most user-friendly Text / Reference book.

Each chapter of the proposed book is also supplemented by solved numerical problems, probable question banks and summary sheet at a glance for better understanding as well as application of the thoughts / systems for practical uses.
