Abstract
The paper proposes an all-optical 1×M router architecture based on pulse-position-modulation header processing (PPM-HP) scheme for packet routing in all-optical high-speed wavelength division multiplexing (WDM) packet switching network. The router is mainly comprised of all-optical clock extraction, pulse-position-modulation header extraction, continuous-wave (CW) sources, wavelength conversion modules and a multiple-wavelength PPM routing table (MW-PPRT). The proposed MW-PPRT uses only a single-bitwise optical AND-gate to carry out fast correlation between the packet header and entire possible entries in the routing table. In addition, MW-PPRT offers the capability of simultaneously generating the routing table patterns for parallel header processing in PPM-HPs. The proposed router is investigated and simulated to show the ultrafast processing, wavelength routing and the optical signal-to-noise ratio (OSNR) performance.
