Fiber Bragg gratings in multicore fibers have significant potential as compact and robust filters for research and commercial applications. With the aid of an innovative, flat-fielded Mach-Zehnder interferometer, we demonstrate deep (>30 dB) narrow (100pm at 3 dB; 90pm at 10 dB) notches in the outer 6 cores of a 7-core fiber at a constant wavelength ( ± 15pm). This is a crucial step in the development of FBGs operating within multimode fibers that carry an arbitrary number of spatial modes.
