Electrooptic Properties of Dielectric Waveguides

In this chapter, the electrooptic properties of the ion beam produced optical waveguides are demonstrated, including the ion beam property modification and the electrooptic devices with different designs and functions. Section 6.1 summarizes the modified electrooptic coefficients of dielectrics by diverse ion beam techniques. Section 6.2 introduces electrooptic modulators based on dielectric waveguides. Sections 6.3 and 6.4 overview the up-to-date progress on electrooptic modulators based on thin films and on-chip devices, including freestanding and wafer bonded membranes of LiNbO3.
