Abstract

CeO₂ thin films were grown on MgO(001) single-crystal substrates by pulsed laser deposition. The CeO₂ thin films were used as a cladding layer of a Bi₄Ti₃O₁₂ thin film waveguide. Structural properties of the BTO/CeO₂MgO heterostructures were investigated using x-ray diffraction techniques. An epitaxial relationship of BTO(001)//CeO₂(001)//MgO(001) and BTO[100]//CeO₂[100]//MgO[001] was confirmed. From the epitaxial heterostructure, a ridge waveguide was fabricated by photolithographic and ion-milling techniques. An single-mode near-field pattern was observed using an end-fire coupling method.
