Abstract

An analysis is made of the effect of tiled-poling-induced birefringence on the polarization conversion in single mode waveguides. A polarization-independent electro-optic modulator with continuous-electrode structure for high speed modulation is designed by using formulae deduced from coupled mode theory. This device uses a Mach-Zehnder structure where both arms are constructed using tilted poling. The same device can be operated in two different modes. One is common-mode which has the advantage of polarization preserving, while the other is differential- mode which features a low driving voltage. An estimation of the influence of misalignment of the poling electrodes on the extinction ratio shows a large fabrication tolerance.
