摘      要：In this article,we review recent advances in the technology of writing fiber Bragg gratings(FBGs)in selected cores of multicore fibers(MCFs)by using femtosecond laser *** writing technology of such a key element as the FBG opens up wide opportunities for the creation of next generation fiber lasers and sensors based on *** advantages of the technology are shown by using the examples of 3D shape sensors,acoustic emission sensors with spatially multiplexed channels,as well as multicore fiber Raman lasers.
