A programmable chirp optical modulator is provided having programs modes of chirp. The modulator includes an optical modulation chip substrate having an electrooptic property; a waveguide that runs across the optical modulation chip, wherein the waveguide includes a first main channel branching into separate parallel first and second waveguide arms that combine into a second main channel; a first coplanar-strip electrode overlying and running along the first waveguide arm; a second electrode overlying and running along the second waveguide arm; and at least one programmable electrode overlying the substrate and adjacent to the second electrode on a side of the second coplanar-strip electrode opposite a side of the second coplanar-strip electrode where the first coplanar-strip electrode is located. The at least one programmable electrode runs in parallel with the second electrode as the second electrode runs along the second waveguide arm.
