<p><P>PROBLEM TO BE SOLVED: To provide a ZnTe crystal effective as an E/O element for a terahertz electromagnetic wave detector of a higher sensitivity by improving a method for sticking together a ZnTe crystal of a plane direction (100) or near the same and a ZnTe crystal of a plane direction (110) or (111) or near the same. <P>SOLUTION: The electrode-optic crystal (E/O crystal) is made by sticking together, by thermocompression bonding, the first crystal (for example, the ZnTe crystal) having a relatively great double refractive index by an electric field, for example, the plane direction of (110) or (111) or near the same and the second crystal (for example, the ZnTe crystal) having a smaller change in the double refractive index by the electric field as compared to the above crystal, for example, the plane direction of (100) or near the same. <P>COPYRIGHT: (C)2003,JPO</p> |
