| 摘要 |
The present invention relates to a routing address encoder, a routing controller, and a routing switch, which decrease the number and the length of optical splitting and optical delay line at optical routing circuits in optical communication network. A routing address encoder in accordance with an embodiment of the present invention includes a pulse generator, an external modulator, an optical address generator, an address selection signal generator, an optical switch, and optical OR gate means. An optical routing circuit for decoding optical routing information received from optical communication network and routing optical signals on the basis of routing address is provided. An optical routing circuit includes an optical splitter, a routing controller, and a routing switch.
