Abstract-A full-wave finite-element method with hybrid edge/ nodal elements is, for the first time, applied to investigating the frequency dispersion of microwave propagation characteristics of broad-band traveling-wave (TW) optical modulators using planar electrode configurations. In order to produce a two-step analysis of electrooptic modulation of optical waveguides, the microwave electrode solver is linked to the optical waveguide solver. Numerical results are shown for an ultrabroad-band TW LiNbO 3 Mach-Zehnder optical modulator with a ridge structure, and the necessity of using the full-wave solver is verified by comparing the calculated 3-dB bandwidth and half-wavelength voltage with the experimental data.Index Terms-Coplanar waveguide, finite-element method, fullwave analysis, microwave photonic device, traveling-wave optical modulator.

“…The guidance in the Ti: LiNbO 3 waveguide was simulated by applying the diffusion model 9 and the beam propagation method. Based on material properties and known physical constants, the refractive index change was evaluated as a function of four main fabrication parameters, namely, Ti strip width and thickness as well as diffusion duration and temperature.…”

Abstract. The design and fabrication of an integrated waveguide polarizer in z-cut LiNbO 3 crystals are reported. Singlepolarization guiding is achieved by careful selection of Ti diffusion parameters exploiting the transverse electric/ transverse magnetic ͑TE/TM͒ refractive index anisotropy. Fabricated Ti: LiNbO 3 waveguide polarizers of 1.5 cm length exhibit less than 0.2-dB/ cm propagation loss at TM and 33-dB extinction ratio as measured at 1.55-m wavelength.
