Abstract

An optical connector assembly may include a first housing having a first opening therein, a second housing having a second opening therein, a first optical window carried by the first housing within the first opening, a second optical window carried by the second housing within the second opening, at least one Vertical Cavity Surface Emitting Laser (VCSEL) carried within the first housing behind the first optical window, and at least one photodetector carried within the second housing behind the second optical window. A first magnetic member may be carried by the first housing, and a second magnetic member may be carried by the second housing and configured to cooperate with the first magnetic member to bias the first and second housings together so that the at least one VCSEL and the at least one photodetector are in optical alignment.

First claim

That which is claimed is:

1. An optical connector assembly comprising:
a first housing having a first opening therein;
a second housing having a second opening therein;
a first optical window carried by said first housing within said first opening;
a second optical window carried by said second housing within said second opening;
at least one Vertical Cavity Surface Emitting Laser (VCSEL) carried within said first housing behind said first optical window;
at least one photodetector carried within said second housing behind said second optical window;
a first magnetic member carried by said first housing; and
a second magnetic member carried by said second housing and configured to cooperate with said first magnetic member to bias said first and second housings together so that said at least one VCSEL and said at least one photodetector are in optical alignment.

2. The optical connector assembly of claim 1 wherein at least one of said first and second magnetic members comprises at least one electromagnet.

3. The optical connector assembly of claim 2 further comprising a controller coupled to said at least one electromagnet and configured to operate said at least one electromagnet to create relative rotational movement between said first and second housings.

4. The optical connector assembly of claim 2 further comprising a controller coupled to said at least one electromagnet and configured to operate said at least one electromagnet to create an attractive force with respect to the other magnetic member for coupling said first and second housings together.

5. The optical connector assembly of claim 2 wherein said controller is further configured to operate said at least one electromagnet to create a repulsive force with respect to the other magnetic member for decoupling said first and second housings from one another.

6. The optical connector assembly of claim 1 wherein said first housing and said first optical window define a first hermetically sealed chamber for said at least one VCSEL; and wherein said second housing and said second optical window define a second hermetically sealed chamber for said at least one photodetector.

7. The optical connector assembly of claim 1 further comprising respective first and second self-aligning features carried by said first and second housings configured to align said first and second optical housings.

8. The optical connector assembly of claim 1 wherein said first and second housings each comprises a respective clamp feature configured to mechanically secure said first and second housings together.

9. The optical connector assembly of claim 1 wherein said first and second housings each has at least one respective fluid exit port for fluid evacuation when said first and second optical windows come in physical contact with one another.

10. The optical connector assembly of claim 1 wherein said first and second magnetic members each comprises a respective array of magnets positioned adjacent said first and second optical windows.

11. The optical connector assembly of claim 1 further comprising a controller coupled with said transmit laser element and configured to beam steer light output from said at least one VCSEL.

12. The optical connector assembly of claim 1 further comprising a respective inductive power winding carried by each of said first and second housings and configured to inductively transfer power therebetween.

13. The optical connector assembly of claim 1 wherein said first and second housings define at least one light barrel through which said at least one VCSEL and said at least one photodetector are optically aligned.

14. An optical connector assembly comprising:
a first housing having a first opening therein;
a second housing having a second opening therein;
a first optical window carried by said first housing within said first opening;
a second optical window carried by said second housing within said second opening;
at least one laser light transmitter carried within said first housing behind said first optical window;
at least one photodetector carried within said second housing behind said second optical window;
a first magnetic member carried by said first housing and a second magnetic member carried by said second housing and configured to cooperate with said first magnetic member to bias said first and second housings together so that said at least one laser light transmitter and said at least one photodetector are in optical alignment, at least one of said first and second magnetic members comprising at least one electromagnet; and
a controller coupled to said at least one electromagnet and configured to operate said at least one electromagnet to create relative rotational movement between said first and second housings.

15. The optical connector assembly of claim 14 wherein said controller is further configured to operate said at least one electromagnet to create an attractive force with respect to the other magnetic member for coupling said first and second housings together.

16. The optical connector assembly of claim 14 wherein said controller is further configured to operate said at least one electromagnet to create a repulsive force with respect to the other magnetic member for decoupling said first and second housings from one another.

17. The optical connector assembly of claim 14 wherein said first housing and said first optical window define a first hermetically sealed chamber for said at least one laser light transmitter; and wherein said second housing and said second optical window define a second hermetically sealed chamber for said at least one photodetector.

18. The optical connector assembly of claim 14 further comprising respective first and second self-aligning features carried by said first and second housings configured to align said first and second optical housings.

19. The optical connector assembly of claim 14 wherein said first and second housings each comprises a respective clamp feature configured to mechanically secure said first and second housings together.

20. The optical connector assembly of claim 14 wherein said first and second housings each has at least one respective fluid exit port for fluid evacuation when said first and second optical windows come in physical contact with one another.

21. The optical connector assembly of claim 14 wherein said first and second magnetic members each comprises a respective array of electromagnets positioned adjacent said first and second optical windows.

22. A method comprising:
positioning first and second optical connectors adjacent one another;
the first optical connector comprising a first housing having a first opening therein, a first optical window carried by the first housing within the first opening, at least one laser light transmitter carried within the first housing behind the first optical window, and a first magnetic member carried by the first housing;
the second optical connector comprising a second housing having a second opening therein, a second optical window carried by the second housing within the second opening, at least one photodetector carried within the second housing behind the second optical window, and a second magnetic member carried by the second housing and configured to cooperate with the first magnetic member to bias the first and second housings together so that the at least one laser light transmitter and the at least one photodetector are in optical alignment, at least one of
