Abstract

The paper presents numerical analysis of integrated optics structure in the form of planar waveguide based on wide band gap oxide semiconductor material. The theoretical analysis of planar waveguide structure was focused on determination of waveguide properties - effective refractive index as a function of waveguide layer thickness for two type of applied waveguide materials – titanium dioxide TiO₂ or zinc oxide ZnO and with cover layer based on biological liquid modeled as a saline solution – sodium chloride. The theoretical analysis was carried out for three type of substrate materials: BK7 glass, quartz and sapphire. The second step of research was focused on analysis of homogenous sensitivity dNeff/dnac, finally modal field distribution in planar waveguide structure was also presented.
