Patent ID: 7251385

Claim:
An optical interconnection circuit, comprising: an integrated circuit chip; a first circuit block provided on the integrated circuit chip, the first circuit block including a first element emitting a first light and a second element emitting a second light; a second circuit block provided on the integrated circuit chip, the second circuit block including a third element receiving the first light and a fourth element receiving a second light; a first optical waveguide that is provided on the integrated circuit chip, the first optical waveguide optically connecting the first and the third elements; a second optical waveguide that is provided on the integrated circuit chip, the second optical waveguide optically connecting the second and the fourth elements; a common light reflecting frame that reflects the first light and the second light; and a wavelength of the first light emitted by the first element being different from a wavelength of the second light emitted by the second elements, the first circuit block and the second circuit block being optically and electrically connected to each other.
