40-Gb/s colorless tunable dispersion compensator employing a planar lightwave circuit and a deformable mirror with 1000- ps/nm tuning range

We propose and demonstrate a tunable dispersion compensator consisting of a waveguide grating router and a deformable mirror. It has a 100-GHz free-spectral range and an adjustment range of 1000 ps/nm for 40-Gb/s signals.
