Abstract
A self-routing switching node that includes an optical associative memory processor that receives packet header information and a switching array coupled to the optical associative memory processor. The switching array receives control signals from the optical associative memory processor. The self-routing switching node also includes a buffer memory coupled to the optical associative memory processor that stores data packet information. The self-routing switching node further includes a vertical cavity surface emitting laser that transforms electronic packet header information into optical header information.
