A new concept for optical filters for pulse compression in optical communication systems is presented. The
effect of filtering is not based on resonances as used in Bragg gratings, but it is achieved by interferences
of parts of the optical wave. The filter consists of three strip loaded dielectric waveguides. Besides two
amplification regions, there are two herringbone like grating structures. The first grating pair delivers the
dispersion behavior of the filter. The second grating pair is a bandpass which should improve the amplitude
response of the filter. The gratings can be built up as a single or multi channel filter. Besides a theoretical
analysis of the filter, the performance of the structure will be presented. It will be shown that not only high
dispersion values can be reached, but additionally a signal amplification is possible.
