| Outline of Final Research Achievements |
Lithium Niobate (LiNbO3, LN)) crystal is a promising photonic material because of its excellent electro-optical and nonlinear optical effects. In this study, we introduces the application of ultra-precision ductile-mode cutting method to the fabrication of strongly confined LN ridged waveguides. As the result, ridged waveguides with ultra-smooth sidewalls (RMS: < 5 nm) were obtained in LN crystals. In addition, we demonstrated preparation of bonded LN thin films on Si substrates by transfer bonding in air for LN/Si hybrid photonic devices.
