Paper Abstract

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.
