ABSTRACT:
An optical signal processing apparatus includes a plurality of plates disposed in parallel at spatial intervals and light LSIs mounted on each of the plates. The transfer of signals in the direction parallel to the surfaces of the plates is performed by lead wires electrically interconnecting the light LSIs. The transfer of signals in the direction normal to the surfaces is performed by the light emitted and received by the light LSIs.
