Abstract
Pure phase modulators are key building blocks for Photonic Integrated Circuits (PICs). Si modulators based on plasma dispersion suffer from spurious amplitude modulation and high insertion losses. Thin-film electro-optic devices relying on the Pockels effect have therefore been proposed as an ideal alternative for phase modulators on Si. Strongly electro-optic thin films of ferro-electric Lead Zirconate Titanate (PZT) grown on Si waveguides allow for Hybrid PZT/Si phase modulators. We present here simulation studies of a co-planar TE/TM modulator structure. |
