SOLID-STATE OPTICAL INTERFEROMETER |
摘要 |
In a solid-state optical interferometer having a light path composed of a loop-shaped optical fiber and a solid-state light wave guide optically coupled to said optical fiber, electrodes for producing a surface acoustic wave (SAW) are formed as a pair on a surface of a substrate on which said solid-state light wave guide is formed, and said surface acoustic wave is used to apply optical modulation to a light beam passing through said solid-state light wave guide. |
