Abstract
An optical connection structure includes a first focus lens arranged between a first light incidence/emission end and an optical element, and a second focus lens arranged between a second light incidence/emission end and the optical element. The first focus lens and the second focus lens are arranged on an optical axis connecting the first light incidence/emission end and the second light incidence/emission end.
Claims16
An optical connection structure comprising:
- a first optical waveguide having a first light incidence/emission end face;
- a second optical waveguide having a second light incidence/emission end face facing the first light incidence/emission end face of the first optical waveguide;
- an optical element between the first light incidence/emission end face and the second light incidence/emission end face;
- a focus lens between the first light incidence/emission end face and the optical element or between the second light incidence/emission end face and the optical element, wherein the focus lens is disposed on an optical axis that connects the first light incidence/emission end face and the second light incidence/emission end face;
- and
- a resin layer having a refractive index different than a refractive index of the focus lens, the resin layer being filled in between the first light incidence/emission end face and the optical element or between the second light incidence/emission end face and the optical element, wherein the focus lens is embedded in the resin layer.
