Abstract
An ultrahigh-speed photonic access node using optical code-based photonic add-drop multiplexing (PADM) and its novel applications to optical data networking are proposed. PADM processes a photonic label of packet,which is mapped onto an optical code, and adds-drops the packet from or to the node, or bypasses the node. PADM is distinct from conventional wavelength ADM (WADM) in that it can handle traffic on a packet-by-packet basis. In the application of PADM to optical data networking, pseudo-time division multiple access (TDMA) and rate-controlled asynchronous access are proposed. The analyses and their numerical simulations of the performances are presented. The simulation results demonstrate low packet-loss probability. Their optical implementations are also demonstrated, in which exploit parallel photonic label processing shows the applicability of proposed optical data networking in an ultrahigh-speed regime.
