We have designed and fabricated a Ti:LiNb03 waveguide high speed Mach-Zehnder interferometric modulator operating at 1.3 um wavelength. Design considerations for optical waveguide and traveling-wave coplanar-waveguide electrode have been listed. The modulator was optimized with respect to optical insertion loss, switching voltage or drive power, and modulation bandwidth. The fiber-pigtailed device had a 5 dB fiber-to-fiber loss and an intrinsic modulation bandwidth of 18 GHz. The voltage required to switch the device from the on- to off-state was measured to be 9.5 V, with an on/off extinction ratio of 33 dB.
