Abstract

Optical connectors that substantially preserve alignment and are easy to manufacture. The alignment system using the optical connectors disclosed herein include a first housing, a second housing and an alignment component, the said alignment component configured to provide optical alignment between the optical components.

First claim

What is claimed is:

1. An optical alignment system comprising:
a first housing comprising:
an inner surface defining an interior volume;
an outer surface;
at least one first optical component;
said first housing configured to mount said at least one first optical component;
a second housing comprising:
an inner surface defining an interior volume;
an outer surface;
at least one second optical component;
said second housing configured to mount said at least one second optical component; and,
an indirect alignment component;
at least one of the outer surfaces of the first or second housings having alignment datums;
said alignment datums being at preselected locations of the at least one of the outer surfaces of the first or second housings;
said indirect alignment component configured to align said first housing;
said indirect alignment component configured to align said second housing;
said indirect alignment component configured to provide alignment between said first housing and said second housing and between said at least one first optical component and said at least one second optical component; wherein said indirect alignment component comprises a spring clip; contact end-points of said spring clip with one of the first housing or the second housing being substantially coincident with at least some of the alignment datums; contact end points being points at an end of a segment of the spring clip that make contact with one of the first housing or the second housing; said alignment datums being configured to substantially surround the contact end-points.

2. The optical alignment system of claim 1 wherein said indirect alignment component comprises a mechanism.

3. The optical alignment system of claim 1 wherein said indirect alignment component is configured to provide tip-tilt alignment of the said first housing and said second housing.

4. The optical alignment system of claim 1 wherein said indirect alignment component comprises a spring clip; wherein said spring clip is configured to expand to accept at least one of said first housing or said second housing.

5. An optical alignment system comprising:
a first housing comprising:
an inner surface of the first housing defining an interior volume;
an outer surface of the first housing;
said first housing configured to mount at least one first optical component;
a second housing comprising:
an inner surface of the second housing defining an interior volume;
an outer surface of the second housing;
said second housing configured to mount at least one second optical component;
at least one of the outer surfaces of the first or second housings having alignment datums;
said alignment datums being at preselected locations of the at least one of the outer surfaces of the first or second housings;
and,

an indirect alignment system;
said indirect alignment system comprising a first indirect alignment subsystem and a second indirect alignment subsystem;
said first indirect alignment subsystem configured to align said first housing;
said second indirect alignment subsystem configured to align said second housing;
said first indirect alignment subsystem and said second indirect alignment subsystem configured to provide alignment between said first housing and said second housing;
wherein at least one of said first indirect alignment subsystem or said second indirect alignment subsystem comprises a spring clip; contact end-points of said spring clip with one of the first housing or the second housing being are substantially coincident with at least some of the alignment datums; contact end points being points at an end of a segment of the spring clip that make contact with one of the first housing or the second housing; said alignment datums being configured to substantially surround the contact end-points.

6. The optical alignment system of claim 5 wherein said first indirect alignment subsystem and said second indirect alignment subsystem are configured to provide tip-tilt alignment of said first housing and said second housing.

7. The optical alignment system of claim 5 wherein said at least one first optical component comprises at least one of a lens, an optical imager, an infinite conjugate imager, a mirror, a grating, an optical fiber, an optical waveguide, a detector, an emitter, a VCSEL, or an optoelectronic device; and at least one second optical component comprises at least one of a lens, an optical imager, an infinite conjugate imager, a mirror, a grating, an optical fiber, an optical waveguide, a detector, an emitter, a VCSEL, or an optoelectronic device.

8. The optical alignment system of claim 1 wherein said at least one first optical component comprises at least one of a lens, an optical imager, an infinite conjugate imager, a mirror, a grating, an optical fiber, an optical waveguide, a detector, an emitter, a VCSEL, or an optoelectronic device; and at least one second optical component comprises at least one of a lens, an optical imager, an infinite conjugate imager, a mirror, a grating, an optical fiber, an optical waveguide, a detector, an emitter, a VCSEL, or an optoelectronic device.

9. The optical alignment system of claim 5 wherein said first indirect alignment subsystem and said second indirect alignment subsystem are configured to provide rotational alignment of said first housing and said second housing.

10. The optical alignment system of claim 5 wherein said first indirect alignment subsystem and said second indirect alignment subsystem are configured to provide rotational and tip-tilt alignment of said first housing and said second housing.

11. The optical alignment system of claim 1 wherein said indirect alignment component is configured to provide rotational alignment of the said first housing and said second housing.

12. The optical alignment system of claim 1 wherein said alignment datums comprise indentations at the preselected locations of the at least one of the outer surfaces of the first or second housings.

13. The optical alignment system of claim 5 wherein said alignment datums comprise indentations at the preselected locations of the at least one of the outer surfaces of the first or second housings.

14. The optical alignment system of claim 5 wherein said first indirect alignment subsystem and said second indirect alignment subsystem are configured to provide tip-tilt alignment of said first housing and said second housing.

15. The optical alignment system of claim 1 wherein contact areas of said spring clip comprise substantially rounded surfaces, said contact areas comprising said contact end-points.

16. The optical alignment system of claim 5 wherein contact areas of said spring clip comprise substantially rounded surfaces, said contact areas comprising said contact end-points.

17. An optical alignment system comprising:
a housing;
said housing further comprising an outer surface;
an optical component;
said optical component mounted to said housing;
said outer surface having alignment datums;
said alignment datums being at preselected locations on said outer surface;
