| 英文摘要 | An optical transmission-reception system includes: a light-emitting element having a first semiconductor multilayer structure with a ring- or disk-like shape and generating a first optical signal and a second optical signal rotating in a direction opposite to the first optical signal; a first optical waveguide optically coupled with the light-emitting element and propagating the first optical signal; a second optical waveguide optically coupled with the light-emitting element and propagating the second optical signal; and a light-receiving element having a second semiconductor multilayer structure with a ring- or disk-like shape, optically coupled with the first and second optical waveguides, and optically receiving the first and second optical signals. The first optical waveguide has a spiral shape at a coupling part with the light-receiving element, and the second optical waveguide has a spiral shape winding in the same direction as the first optical waveguide at a coupling part with the light-receiving element. |
