A novel multitap optical transversal signal processor based on wavelen
gth multiplexed Bragg grating arrays is presented, This structure enab
les the realization of a large number of taps for obtaining sharp band
pass filtering with high resolution and also enables arbitrary tap wei
ght profiles to be obtained. Results on a 4-GHz, 29-tap filter demonst
rates a sharp bandpass filter response, and windowing techniques on th
e tap profiles are demonstrated to enhance the sidelobe suppression ch
aracteristics.
