Abstract:
An optical circuit substrate including optical wiring which drives an electro-optic optical switch or optical modulator provided on the optical circuit substrate by a voltage of a transistor in the LSI and/or an electrode connected to the same, picks up at least part of the light of a light power source or a waveguide, and thereby converts the output electrical signal of the transistor in the LSI to an optical signal, transmits the optical signal through a waveguide or spatial medium, converts this to an electrical signal by a light receiving element provided on the optical circuit substrate, light receiving element provided in an LSI, or light receiving element mounted on the optical circuit substrate, and thus transmits the signal to a transistor in the same or another LSI and/or an electrode connected to the same.
