| 英文摘要 | An optical device having a large extinction ratio and being suitable for the digital operation including first and second electrodes (7, 8) formed on both sides of a waveguide structure, respectively such that a carrier-injection region (3a) and a non-carrier injection regions (3b) are formed adjacent to each other in the waveguide structure. When mass carriers are stored in the carrier injection region, its refractive index is reduced lower than the non-carrier-injection regions. In this state, when a light wave with low optical power propagates through the carrier-injection region, since an amount of carriers consumed thereby is small, the refractive index of this region is still lower than the non-carrier-injection regions, and the input light wave is emitted sideways through the non-carrier-injection region. In contrast, when a light wave with high optical power propagates through the carrier-injection region, since the carrier consumption is large, the refractive index of this region (3a) becomes higher than the non-carrier-injection regions (3b), and the input light propagates through a waveguide which is optically induced to extend from the incident surface to the exit surface. |
