Embodiment Construction

[0028] figure 1 Indicates the mixed light backplane or PCB 1, which is a stack consisting of several layers. Hereinafter, this base plate 1 is also referred to as laminate 1 . Laminate 1 comprises at least: an optical waveguide 2, and it can be the partial waveguide structure 3 that comprises a plurality of waveguides 2 (see Figure 3A ). Waveguide 2 is placed perpendicular to figure 1 in the x-y plane of the midplane. The waveguide 2 or waveguide structure 3 is integrated or embedded in at least one layer of the stack 1 . The embedded waveguide 2 can be a polymer waveguide, a glass sheet waveguide or a waveguide made by embedded optical fiber technology.

[0029] The optical signal is transferred to or from a cooperating optical device, e.g. an optical or optoelectronic device 4 or another PCB 5, which is on a first optical path 6 of a waveguide 2 in the stack 1, which provides a second optical path for the optical signal Process 7. In order to achieve optimum optical ...

Abstract

The present invention relates to an optical connector assembly for optical connection to a waveguide structure in the x-y plane of a stack, wherein the connector assembly includes coupling means providing a first optical path from which the waveguide structure provides second optical path. The coupling means comprises a first reference means adapted to cooperate with a second reference means in the stack, wherein the second reference means is adapted to align the coupling means with the waveguide structure in the x-y plane along the x-direction and the y-direction in order to Optically coupling the first optical path and the second optical path. Accordingly, an optical connector assembly is provided that improves optical coupling between the waveguide structure and the optical path in the coupling device and / or mating optical device. The coupling means may comprise third reference means coupling the optical connector and the waveguide structure. The invention also relates to a method of aligning a coupling device and a waveguide structure.

Description

technical field [0001] The present invention relates to an optical connector assembly for optical connection to at least one waveguide structure in at least one x-y plane of a stack, said connector assembly comprising coupling means providing at least a first optical path, said waveguide structure comprising at least one An optical waveguide providing at least a second optical path deflected from said first optical path, said coupling means including first reference means adapted to cooperate with a second reference means in said stack.
