Tilted fiber Bragg gratings in multicore optical fibers for optical sensing [PDF]
Optics Letters, 2017 We have inscribed a tilted fiber Bragg grating (TFBG) in selected cores of a multicore optical fiber. The presence of the TFBG permits to couple light from the incident-guided mode to the cladding modes and to the neighbor cores, and this interaction can be used for optical sensing.
