摘要

A time division multiplexing of 106 weak fibers Bragg gratings (FBGs) based on a ring resonant-cavity is demonstrated.A semiconductor optical amplifier is connected in the cavity to function as an amplifier as well as a switch.The 106 weak FBGs are written along a SMF-28 fiber in serial with peak reflectivity of about-30 dB and equal separations of 5 m.The crosstalk and spectral distortion are investigated through both theoretical analysis and experiments.
