The review covers the 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 cladding modes excitation in such structures is discussed, and the main properties of TFBGs are considered. Special attention is paid to the sensing applications of TFBGs, including data processing methods for TFBG sensing systems. The fabrication process of tilted fiber Bragg gratings is described, as well as the method of thin metal films deposition onto the side surface of the fiber.
