ELECTRO-OPTIC EFFECT ELEMENT AND METHOD FOR MANUFACTURING THE SAME |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To reduce the internal stress accompanying a piezoelectric effect and the residual stress in deposition relating to an electro-optic effect element and a method for manufacturing the same. <P>SOLUTION: A material having the electro-optic effect is formed as a slab optical waveguide 2 and grooves 3 are formed in the side parts of the refractive index changing regions formed by the voltage impression to the slab optical waveguide 2 so as not to hinder the optical paths for light signals. <P>COPYRIGHT: (C)2004,JPO</p> |
