Abstract

Claims (31)

1. A method of forming an optical coupling device on a substrate, said method including:

forming a stress relief layer on said substrate

producing, on said stress relief layer, an optically transparent body with a surface having a plurality of steps by disposing a material onto said stress relief layer, contacting said material with a template having a stepped recess formed therein and solidifying said material by exposing said material to actinic radiation.

2. The method as recited in claim 1 wherein producing further includes disposing said material with an acrylate component selected from a set of acrylates consisting essentially of ethylene diol diacrylate, t-butyl acrylate, bisphenol A diacrylate, acrylate terminated polysiloxane, polydifluoromethylene diacrylate, perfluoropolyether diacrylates and chlorofluorodiacrylates.

3. The method as recited in claim 1 wherein producing further includes disposing said material with a silylated component selected from a group consisting essentially of (3-acryloxypropyltristrimethylsiloxy) silane.

4. The method as recited in claim 1 further including fabricating said substrate from optically transparent material.

5. The method as recited in claim 1 wherein forming further includes fabricating said stress relief layer from rubbers of a set of rubbers consisting essentially of polysiloxane rubber and fluorosilocane rubber.

6. The method as recited in claim 1 wherein producing further includes disposing, on said stress relief layer, said material consisting essentially of ethylene diol diacrylate and an initiator.

7. The method as recited in claim 1 wherein producing further includes disposing, on said stress relief layer, said material consisting essentially of 1,3-bis(3-methacryloxypropyl)tetramethyldisiloxane and an initiator.

8. The method as recited in claim 1 wherein producing further includes disposing, on said stress relief layer, said material consisting essentially of (3-acryloxypropyl)tris(tri-methoxysiloxy)-silane, ethylene dio diacrylate, t-butyl acrylate, and an initiator.

9. The method as recited in claim 1 wherein producing further includes disposing, on said stress relief layer, said material consisting essentially of acrylate terminated poly siloxane, t-butyl acrylate, and an initiator.

10. The method as recited in claim 1 wherein producing further includes disposing, on said stress relief layer, said material consisting essentially of bisphenol A diacrylate, and an initiator.

11. A method of forming an optical coupling device on a substrate, said method including:

forming said substrate with a stress relief layer;

disposing a material onto said stress relief layer that is polymerizable in response to actinic radiation;

forming a plurality of spaced-apart stacks of said material by contacting said material with a template have a stepped-recess formed therein; and

solidifying said plurality of spaced-apart stacks of said material into an optically transparent body with a surface having a plurality of steps by subjecting said stacks to actinic radiation.

12. The method as recited in claim 11 wherein disposing said material on said stress relief layer further includes disposing said material on said stress relief layer, being formed from rubbers of a set of rubbers consisting essentially of polysiloxane rubber and fluorosilocane rubber.

13. The method as recited in claim 12 further including fabricating said substrate from optically transparent material.

14. The method as recited in claim 13 wherein disposing further includes disposing said material with an acrylate component selected from a set of acrylates consisting essentially of ethylene dio diacrylate, t-butyl acrylate, bisphenol A diacrylate, acrylate terminated polysiloxane, polydifluoromethylene diacrylate, perfluoropolyether diacrylates and chlorofluorodiacrylates.

15. The method as recited in claim 13 wherein disposing further includes disposing said material with a silylated component selected from a group consisting essentially of (3-acryloxypropyltristrimethylsiloxy) silane.

16. A method of forming an optical coupling device on a substrate, said method including:

forming, on said substrate, a stress relief layer formed from rubbers of a set of rubbers consisting essentially of polysiloxane rubber and fluorosilocane rubber;

disposing a material, onto said stress relief layer, that is polymerizable in response to actinic radiation;

forming a plurality of spaced-apart stacks of said material by contacting said material with a template having a stepped-recess formed therein; and

solidifying said plurality of spaced-apart stacks of material into an optically transparent body with a surface having a plurality of steps by subjecting said stacks to actinic radiation.

17. The method as recited in claim 16 wherein disposing further includes depositing said material from a set of materials consisting essentially of ethylene dio diacrylate and an initiator.

18. The method as recited in claim 16 wherein disposing further includes depositing said material from a set of materials consisting essentially of 1,3-bis(3-methacryloxypropyl)tetramethyldisiloxane and an initiator.

19. The method as recited in claim 16 wherein disposing further includes depositing said material from a set of materials consisting essentially of (3-acryloxypropyl)tris(tri-methoxysiloxy)-silane, ethylene dio diacrylate, t-butyl acrylate, and an initiator.

20. The method as recited in claim 16 wherein disposing further includes depositing said material from a set of materials consisting essentially of acrylate terminated poly siloxane, t-butyl acrylate, and an initiator.

21. The method as recited in claim 16 wherein disposing further includes depositing said material from a set of materials consisting essentially of bisphenol A diacrylate, and an initiator.
