Title: Formation of microcycle domain reversing structure
Inventor: ISOBE CHIHARU
IPC: G02F1/355
Filed: 1989-11-24
Abstract: PURPOSE:To easily form the microcycle domain reversing structure hardly damaged by light without causing the refractive index change with good reproducibility by forming the Nb layer of a microcycle pattern on an LiNbO3 substrate and heat-treating the layer in an oxygen atmosphere to form a microcycle domain reversing structure on the substrate surface. CONSTITUTION:An Nb layer 2 of a microcycle pattern is formed on the LiNbO3 substrate 1 (LN substrate), and then heat-treated in an oxygen atmosphere to form a microcycle domain reversing structure 3. In this case, the Li element on the surface of the LN substrate 1 unmasked with the Nb layer 2 is converted to Li2O and discharged outside the substrate, hence the Li element concn. at the unmasked part is reduced, the Curie point at that part is lowered, an electric field is generated at the interface, spontaneous polarization is caused, and the reversed domain part is generated. As a result, the microcycle domain reversing structure 3 hardly damaged by light is formed with good reproducibility without causing a change in the refractive index of the LN substrate 1.
