Abstract: This document describes an electro-optic modulator with an integrated memory device comprising a micro-ring resonator and the memory device comprising a ferroelectric capacitor disposed in a partial circumference of a raised ring waveguide of the micro-ring resonator. An electric field is generated between transparent electrodes of the ferroelectric capacitor when a voltage is applied between these two layers, whereby the electric filed causes a polarization state of the ferroelectric capacitor to change based on the strength of the electric field. The electric field then extends between the ferroelectric capacitor and a bottom electrode layer of the micro-ring resonator when the applied voltage is removed, causing a refractive index of a non-centrosymmetric material of the micro-ring resonator to change based on the strength of the extended electric field.

Abstract: A structure for an optoelectronics platform and a method of fabricating a structure for an optoelectronics platform such as a Mach-Zehnder modulator or a waveguide. The method comprises the steps of providing a substrate, and depositing a BaTi03, BTO, film on a surface of the substrate and having a thickness suitable for single mode operation with one or more possible polarization configurations with optical confinement in the BTO film at a wavelength or wavelength range of operation; wherein the substrate is chosen to provide vertical refractive index confinement in a direction perpendicular to the surface of the substrate for the single mode operation optical confinement in the BTO film at the wavelength or wavelength range of operation.
