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.

Disclosed herein is a material that may be useful as a coating for optical slides and medical implants. The material may aid or restrict grown of cells on a coating of the composite material. As such, there is provided a composite material having a substrate on the surface of which a coating layer of an amorphous metal oxide is formed. The metal oxide may be one or more of AgO, ZnO, ZrO, TiO, CuO, and YOand the coating layer may be from 5 to 100 nm thick and have a root mean square roughness of the coating surface is from 0.1 to 0.7 nm.

Thin film deposited inorganic metal oxide as a selective substrate for mammalian cell culture and as an implant coating
