Simplified technique for the design of multichannel dispersion compensation FBG

In this work, we have presented a simple approach to design a multichannel sampled fiber Bragg grating (SFBG) for dispersion compensation, based on groups of SFBG with phase modulation between groups. We present also an apodization technique that minimizes the high group delay ripple that occurs with this approach. To demonstrate an application, was made a simulation that represented a real case of multichannel dispersion compensation.
