Summary form only given. This paper describes active delay line devices constructed using hybrid semiconductor/passive optical waveguide technology. The application of these devices to derivation of a timing reference pulse and all-optical header recognition and self-routing of ultrafast packages with multibit addresses is demonstrated. The basic functions required to construct an all-optical self-routing asynchronous packet-switched network are developed.
