<p>A colorless, waveguide-grating-router-based tunable dispersion compensator includes a planar lightwave circuit and a deformable mirror (108), optically coupled to each other by a plano-cylindrical glass lens (106) such that a fast tuning speed and single-knob dispersion adjustment are obtained. In a further aspect of the present invention, the waveguide-grating router is pinched, symmetrical about its center line, and has a half-wave plate inserted therein to provide polarization independence. In a still further aspect of the present invention, the deformable mirror includes, reflective film attached to opposing piezo-electric actuators.</p> |
