Abstract

An optical connection assembly joining optical components is described. The optical connection assembly is manufactured using a fan out wafer level packaging to produce dies/frames which include mechanical connection features. A fastener is joined to a connection component and affixed to the mechanical connection features, to provide structural support to the connection between the connected component and the die/frame structure.

Claims (36)

1. An optical connection assembly, comprising:

a framing component comprising a mechanical connection feature, wherein the mechanical connection feature comprises a first hole and a second hole;

a photonic element comprising an optical feature, wherein the photonic element is affixed to the framing component;

an optical connector optically connected to the optical feature in the photonic element, wherein the optical connector comprises an external contact point; and

a fastener affixed to the framing component via the mechanical connection feature, wherein the fastener is joined to the external contact point to establish a mechanical connection between the optical connector and the photonic element, wherein the fastener comprises a first insertion section and a second insertion section, and wherein the first insertion section is inserted in the first hole and the second insertion section is inserted in the second hole, and wherein the optical connection assembly further comprises a joining material disposed on the first insertion section, the first hole, the second insertion section, and the second hole to secure the fastener to the framing component.

2. The optical connection assembly of claim 1 , wherein the photonic element comprises at least one alignment feature, wherein the alignment feature provides an alignment between the photonic element and alignment features of the optical connector; and

wherein the optical connector is directly optically connected to the optical feature in the photonic element.

3. The optical connection assembly of claim 1 , further comprising:

an optical adapter affixed to the photonic element and framing component, wherein the optical adapter comprises:

at least one alignment feature wherein the alignment feature provides an alignment between the optical adapter and alignment features of the optical connector.

4. The optical connection assembly of claim 3 , wherein the optical adapter is disposed on the photonic element, and wherein the optical connector is directly optically connected to the optical feature in the photonic element.

5. The optical connection assembly of claim 3 , wherein the optical adapter is disposed between the photonic element and the optical connector,

wherein the optical adapter further comprises adapter optical features, and

wherein the optical connector is optically connected to the optical feature in the photonic element via the adapter optical features.

6. The optical connection assembly of claim 1 , wherein the fastener comprises a clamp piece, wherein the clamp piece comprises an attachment portion, wherein the attachment portion is joined to the optical connector at the external contact point.

7. The optical connection assembly of claim 1 , wherein the fastener comprises two clamp pieces, wherein each of the two clamp pieces comprise an attachment portion, wherein the attachment portion of each of the two clamp pieces is joined to the optical connector at the external contact point.

8. The optical connection assembly of claim 1 , wherein the fastener comprises spring sections, wherein the spring sections provide a retaining force to secure the optical connector to the framing component.

9. A photonic connection assembly, comprising:

a photonic element comprising an optical feature and a connection feature, wherein the connection feature comprises a first hole and a second hole;

an optical connector optically connected to the optical feature in the photonic element, wherein the optical connector comprises an external contact point; and

a fastener affixed to the photonic element via the connection feature, wherein the fastener is joined to the external contact point to secure the optical connector to the photonic element, wherein the fastener comprises a first insertion section and a second insertion section, and wherein the first insertion section is inserted in the first hole and the second insertion section is inserted in the second hole, and wherein the photonic connection assembly further comprises a joining material disposed on the first insertion section, the first hole, the second insertion section, and the second hole to secure the fastener to the photonic element.

10. The photonic connection assembly of claim 9 , wherein the connection feature comprises a first connection pad and a second connection pad, wherein the fastener comprises a first section affixed to the first connection pad with a joining material and a second section affixed to the first connection pad with a joining material.

11. The photonic connection assembly of claim 9 , wherein the fastener comprises a clamp piece, wherein the clamp piece comprises an attachment portion, wherein the attachment portion is joined to the optical connector at the external contact point.

12. An optical connection assembly, comprising:

a framing component comprising a mechanical connection feature;

a photonic element comprising an optical feature, wherein the photonic element is affixed to the framing component;

an optical connector optically connected to the optical feature in the photonic element, wherein the optical connector comprises an external contact point;

an optical adapter disposed between the photonic element and the optical connector and affixed to the photonic element and the framing component, wherein the optical adapter comprises at least one alignment feature and adapter optical features, wherein the alignment feature provides an alignment between the optical adapter and alignment features of the optical connector, wherein the optical connector is optically connected to the optical feature in the photonic element via the adapter optical features.

13. The optical connection assembly of claim 12 , wherein the photonic element comprises at least one alignment feature, wherein the alignment feature provides an alignment between the photonic element and alignment features of the optical connector; and

wherein the optical connector is directly optically connected to the optical feature in the photonic element.

14. The optical connection assembly of claim 12 , wherein the fastener comprises a clamp piece, wherein the clamp piece comprises an attachment portion, wherein the attachment portion is joined to the optical connector at the external contact point.

15. The optical connection assembly of claim 12 , wherein the fastener comprises two clamp pieces, wherein each of the two clamp pieces comprise an attachment portion, wherein the attachment portion of each of the two clamp pieces is joined to the optical connector at the external contact point.

16. The optical connection assembly of claim 12 , wherein the fastener comprises spring sections, wherein the spring sections provide a retaining force to secure the optical connector to the framing component.

17. The optical connection assembly of claim 12 , wherein the mechanical connection feature in the framing component comprise a first hole and a second hole, wherein the fastener comprises a first insertion section and a second insertion section, and wherein the first insertion section is inserted in the first hole and the second insertion section is inserted in the second hole.

18. The optical connection assembly of claim 17 , wherein the optical connection assembly further comprises a joining material disposed on the first insertion section, the first hole, the second insertion section, and the second hole to secure the fastener to the framing component.
