Optical switch. |
摘要 |
<p>An optical switch with improved stability which has a flat waveguide including at least two optical waveguides which are made of a glass containing silica and arranged closely each other, at least a core part of each of the optical waveguides consisting of an amorphous material which is prepared by a sol-gel method and contains organic molecules doped and orientated in a direction of electrostatic field by the application of an electrostatic field, and means for changing an optical path through change of a refractive index of the core part by applying an external force to the core part, which means is provided near the core part.</p> |
