The phase-velocity mismatch due to material dispersion in traveling-wave LiNbO_3 optical
waveguide modulators may be greatly reduced by breaking the modulation transmission line into short
segments and connecting each segment to its own surface antenna. The array of antennas is then
illuminated by the modulation signal at an angle which produces a delay from antenna to antenna to
match the optical waveguide's delay.
