We have investigated tunable fiber Bragg gratings (TFBGs) for single channel and for dual channels drop applications. The TFBGs are cable of dropping single DWDM channel or two consecutives DWDM channels in 8 nm bandwidth in the C-band. This feature is desirable in metro-edge network applications where low channel count (up to eight) dominates. Extensive stability, reproducibility and system characterization in addition to numerical simulations were conducted to investigate the feasibility of TFBG in optical communication networks.
