Abstract:
The review covers current achievements and prospects for the development of fiber sensorics associated with tilted fiber Bragg gratings (TFBGs), including metal-coated (plasmonic) sensors. The physical nature of the excitation of the cladding modes in such structures is discussed, and the main properties of TFBGs are considered. Special attention is devoted to sensing applications of TFBGs, including data processing methods for TFBG sensing systems. The process of fabricating tilted fiber Bragg gratings is described, as is the method of thin metal film deposition onto the side surface of the fiber.
