A technique for reducing the bias electrical power needed for a chromatic dispersion equaliser on a planar lightwave circuit is presented. We applied a phase trimming technique to silica waveguides to reduce the operating power required for the equaliser. The results from preliminary trimming experiments, in which the equaliser was used to carry out second-order dispersion compensation are presented. The results show a successful reduction in the operating power
