Abstract:
1. An optical waveguide comprising: a slab-type optical waveguide layer; and a plurality of chips which include either an optical input port for inputting an optical signal from the slab-type optical waveguide layer or an optical output port for outputting an optical signal to the slab-type optical waveguide layer, wherein each said optical input port receives the optical signal, output by each said optical output port, from the slab-type optical waveguide layer in accordance with a timing signal inputted using an electrical connection between the plurality of chips, wherein the optical signal output by each said optical output port comprises a packet signal train formed of a finite pulse train, and wherein the timing signal is individually sent as an instruction signal used to select adoption or rejection of the packet signal train; and wherein the timing signal comprises an electrical signal formed for every packet signal train.
