When one or more optical fibers are located and/or secured in one or more corresponding fiber alignment structures of the apparatus, the one or more apparatus alignment features may also enable passive alignment of the one or more optical fibers relative to the member.

An apparatus for positioning one or more optical fibers relative to the apparatus, comprises a body comprising material, and one or more fiber alignment structures defined in the material of the body. Each fiber alignment structure comprises a groove and a corresponding passage. The groove and the corresponding passage are arranged end-to-end. Each fiber alignment structure is configured to accommodate a corresponding optical fiber extending along the groove and the corresponding passage. The groove of each fiber alignment structure may serve or help to guide an end of a corresponding fiber into the corresponding passage during assembly. The groove of each fiber alignment structure may help to support the end of the corresponding optical fiber. The groove of each fiber alignment structure can assist with maintaining a position of the corresponding optical fiber when ribbonised or non-ribbonised optical fiber is used.

An apparatus for positioning one or more optical fibers relative to the apparatus, comprises a body comprising material, and one or more fiber alignment structures defined in the material of the body, wherein each fiber alignment structure is configured to accommodate a corresponding optical fiber, and wherein each fiber alignment structure is configured to induce one or more bends along the corresponding optical fiber. When an optical fiber is located in such a fiber alignment structure, the optical fiber may be forced into contact with the fiber alignment structure in one or more known regions so that the corresponding optical fiber is located at a more predictable position relative to the corresponding fiber alignment structure in the one or more known regions than is the case for known fiber alignment structures. The location of the corresponding optical fiber at a more predictable position may improve the optical coupling efficiency achievable between the optical fiber and an optical component and/or a photonic chip.
