A self-routing system based on the optical asynchronous transfer mode (OATM), optical time division and wavelength division multiplexing (OTDM and WDM) has been studied as a way of realizing the high-speed transmission of large-capacity information.1 In particular, OATM is known to be the most flexible method for the high-speed transmission of cell/packet. The cell/packet routing scheme of a given system has the potential to dramatically increase switching capacities.2–3 However, switching in cell/packet units leads to a high rate of traffic competition in a switch that has multiple input channels. Therefore, cell/packet-traffic competition must be properly controlled so that the system is able to provide a service that is reliable and of good quality to all subscribers. Sensing of the overlap between the cells/packets and traffic control according to an established order of priority are required of self-routing systems. In previously published work, we reported on an all-optical circuit which senses and controls cell competition in an OATM-based switching system.4 The proposed circuit generates buffer-control and switch-control signals to prevent collisions between cells that may overlap in time and are being injected into a switch from multiple channels.
