Abstract
One of optical packets x copied by an optical copying mechanismis converted into an electric packet by an optic/electric converting mechanism. An address information extracting mechanismextracts address information from a header of the packet converted into the electric packet. A control light generating mechanismgenerates a control light based on the extracted address information. The other of the copied optical packets x is delayed by an optical delaying mechanismfor a predetermined time, and entered to a third nonlinear optical effect device. The third nonlinear optical effect deviceswitches a route of the optical packet x based on the control light. The optical packet x is outputted through an optic/electric converting mechanism, a buffer, a multiplexing mechanism, and an electric/optic converting mechanism
