Classification: CPC G | IPC G

Claim 17:
18. An optical connection structure comprising:
a first optical waveguide coupled to a second optical waveguide, the first optical waveguide and the second optical waveguide having different mode fields;
a bridge body bridging the first optical waveguide and the second optical waveguide;
a support having an upper surface and a lower surface, wherein the upper surface is coupled to the bridge body, and wherein a gap is disposed in a center part of the lower surface; and
an optical body in a propagation path of light between the first optical waveguide and the second optical waveguide, wherein the optical body is joined to a lower side of the gap of the support and is configured to change a course of radiation mode light emitted from the first optical waveguide and propagating in a direction away from an optical axis thereof to obtain waveguide mode light passing through the optical body.
