The coherent crosstalk of an add/drop filter with Bragg gratings written in a planar lightwave circuit Mach-Zehnder interferometer is investigated experimentally and theoretically. The filter is used to design an optical local area network without any optical amplifiers, based on the coherent crosstalk limitation.
