The most known active optical material is lithium niobate (LiNbO3). Due to the ferroelectric crystal structure lithium niobate changes its refractive index if an electric field is applied. Another ferroelectric material is potassium titanyl phosphate (KTP or KTiOPO4). KTP's properties also make it superior as an electro-optic modulator, in optical parametric generation, and in optical waveguiding. This paper will give an overview of production steps of integrated optics with proton exchange in lithium niobate and with ion exchange in potassium titanyl phosphate. Basic optic structures and components made for phase and intensity modulation are presented. The application of the integrated optic chips in sensors, telecommunication and color image generation will be addressed.
