Claim 0:
1. A photonics-electronics convergence switch comprising a packet switch and a plurality of optical switches, wherein
the packet switch includes an electronic circuit and a plurality of optical transmitter-receivers provided near the electronic circuit and having a photoelectric conversion function,
the plurality of optical switches include different types of optical switches,
paths connecting between the electronic circuit and the plurality of optical transmitter-receivers are formed of wiring through which an electrical signal passes,
paths connecting between the plurality of optical transmitter-receivers and the plurality of optical switches, paths connecting between two optical switches of the different types out of the plurality of optical switches, and paths connecting between the plurality of optical switches and an input-output port of the photonics-electronics convergence switch are formed of optical waveguides, and
optical switches of the different types out of the plurality of optical switches cooperate to select
a path through which an inputted optical signal is outputted to a different packet switch connected to the packet switch without passing through the electronic circuit,
a path through which an optical signal inputted from the different packet switch is outputted to the different packet switch without passing through the electronic circuit,
a path through which an inputted optical signal passes through the electronic circuit and is subjected to photoelectric conversion by the plurality of optical transmitter-receivers, and the optical signal obtained by the photoelectric conversion is outputted to the different packet switch, and
a path through which an optical signal inputted from the different packet switch passes through the electronic circuit and is subjected to photoelectric conversion by the plurality of optical transmitter-receivers, and the optical signal obtained by the photoelectric conversion is outputted to the different packet switch.
