The dynamics characteristics of picosecond soliton-like pulses
propagating through add-drop optical filters, based on lossless uniform
and Gaussian nonlinear fiber grating couplers, are numerically
investigated under different power levels. To obtain the temporal
profiles, the nonlinear coupled-mode equations, that model these
devices, are solved numerically. These devices can perform the
extraction (drop) of an optical signal, since there is the reflection of
a pulse previously switched between adjacent waveguides. The extraction
efficiency, recurrently better at low power levels, is subordinated to
the matching between the associated spectra of the input pulses and the
hybrid devices analyzed. The switching effects, as well the gratings
responsiveness, impact on the outputs profiles, since diverse temporal
shapes can be obtained. The results reinforce the importance and the
potential of properly engineered structures for all-optical processing
requirements.
