Ferroelectric domain inverted waveguide structure and a method for producing a ferroelectric domain inverted waveguide structure |
摘要 |
A method for producing an optical waveguide part includes the steps of preparing a ferroelectric single crystalline substrate having a polarization-axis substantially parallel to a main surface thereof and having a given ferroelectric domain-inverted pattern, and epitaxially growing a ferroelectric single crystalline film on the ferroelectric single crystalline substrate. The ferroelectric domain-inverted pattern is thereby transcribed from the substrate into the ferroelectric single crystalline film to form a ferroelectric domain-inverted structure therein.
