| 英文摘要 | An optical switch having a plurality of channel waveguides. At least one of which is a gain-guided channel waveguide. In operation, a light beam incident on one end face of the optical switch through one of the channel waveguides exits from the switch through one or another of the channel waveguides in accordance with current injected into the gain-guided channel waveguide. As a result, a compact low-voltage optical switch is possible. The channel waveguides may run parallel to each other, or may come together in a center portion in a X-shape, separated by a relatively small distance, or as a third alternative may be formed in a Y-shape, with a small distance separating the branches of said Y-shape. |
