摘要：
The authors report the first realisation of an integrated-optic variable group-delay dispersion equaliser using a lattice-form programmable optical filter. The equaliser consists of seven tunable couplers and six asymmetrical Mach-Zehnder interferometers cascaded alternately in series. The dispersion can be varied step by step from -923 ps/nm to +653 ps/nm.
