Abstract
A plurality of electric data signals representing parallel data bits are applied to a plurality of gates or control terminals on-off controlling optical switches, respectively. A single pulsed synchronizing signal is distributed to input terminals of the plurality of gates or the optical switches. Synchronizing signals, which have passed through gates or optical switches, which are in an ON state, among the plurality of gates or the optical switches are coupled to synchronize finally an optical signal. In this way a serial optical pulsed output signal can be obtained by utilizing optical delay in a process for distributing the synchronizing signals or a process for coupling the synchronizing signals.
