Abstract: A velocity-matched LiNbO(sub 3) modulator is described which achieves an electrical 3 dB bandwidth of 44 Ghz and an optical 3 dB bandwidth in excess of 50 Ghz. It also utilizes multimode waveguides in the active section to achieve excellent loss, drive voltage, and contrast ratio characteristics over a 1.3 to 1.55 mew m wavelength range.
