We present a review of the fundamentals and applications of fiber optic sensors based on multicore coupled structures. Fiber gratings in optical fibers stand out in sensing solutions due, e., to their immunity to external electromagnetic fields, having a high sensitivity for different sensing parameters, being small in size and thereby allowing integration in many technical structures and with a high possible. The method uses a multicore fiber with differently doped fiber cores and, therefore, enables a selective grating inscription. The concept can be applied in a draw tower inscription process for an efficient production of sensing networks. The MCF comprises three strongly coupled cores; one of such cores is at the geometrical center of the MCF. Further there are many points why fiber optic sensors are used in place of traditional size and. Among the reasons why optical fibers are such an attractive are their low loss, high bandwidth, immunity to electromagnetic interference (EMI), small size, light weight, safety, relatively low cost, low maintenance, etc.
