Abstract

An optical fiber connector includes a fiber alignment body including a continuous optical fiber guide channel extending therethrough. The continuous optical fiber guide channel has a lead-in channel portion, a lead-out channel portion and a turn portion that connects the lead-in channel portion and the lead-out channel portion. The fiber alignment body has a reflective surface formed of metal that receives light traveling from an optical fiber located within the lead-in channel portion of the continuous optical fiber channel and reflects the light into the lead-out channel portion of the continuous optical fiber channel.

Claims (26)

1. An optical fiber connector comprising:

a fiber alignment body including an optical fiber guide channel extending therethrough, the optical fiber guide channel having a lead-in channel portion, a lead-out channel portion and a turn portion that connects the lead-in channel portion and the lead-out channel portion, the fiber alignment body having a reflective surface formed of metal that receives light traveling from an optical fiber located within the lead-in channel portion of the optical fiber guide channel and reflects the light into the lead-out channel portion of the optical fiber guide channel, wherein:

the fiber alignment body comprises:

a first fiber alignment member comprising a lead-in channel portion and a lead out channel portion, wherein the lead-in channel portion of the first fiber alignment member is transverse to the lead-out portion of the first fiber alignment member: and

a second fiber alignment member comprising a lead-in channel portion and a lead out channel portion, wherein the lead-in channel portion of the second fiber alignment member is transverse to the lead-out portion of the second fiber alignment member; and

the first fiber alignment member is connected to the second fiber alignment member such that the lead-in channel portion of the first fiber alignment member and the lead-in channel portion of the second fiber alignment member cooperate to form the lead-in channel portion of the optical fiber guide channel, and the lead-out channel portion of the first fiber alignment member and the lead-out channel portion of the second fiber alignment member cooperate to form the lead-out channel portion of the optical fiber guide channel, and the first fiber alignment member and the second fiber alignment member meet along a parting region that intersects the optical fiber guide channel.

2. The optical fiber connector of claim 1 , wherein the reflective surface is a predetermined shape selected to reflect the light from the optical fiber into the lead-out channel portion of the optical fiber guide channel.

3. The optical fiber connector of claim 2 , wherein the reflective surface is planar or parabolic in shape.

4. The optical fiber connector of claim 1 , wherein the first fiber alignment member comprises a lead-in channel surface, a lead-out channel surface and the reflective surface that extends at an obtuse angle to the lead-in channel surface.

5. The optical fiber connector of claim 1 , wherein the parting region intersects each of the lead-in channel portion, the lead-out channel portion and the turn portion of the optical fiber guide channel.

6. The optical fiber connector of claim 1 , wherein the reflective surface is at the turn portion of the optical fiber guide channel.

7. The optical fiber connector of claim 1 further comprising an optical fiber located in the lead-in channel portion of the optical fiber guide channel.

8. The optical fiber connector of claim 7 , wherein the optical fiber has an end face that faces the reflective surface.

9. The optical fiber connector of claim 7 , wherein the optical fiber includes a cladding comprising an optical material through which light passes after reflecting from the reflective surface.

10. The optical fiber of claim 1 , wherein the reflective surface allows a portion of the light to transmit by the reflective surface.

11. The optical fiber of claim 10 further comprising a photodetector that detects an amount of light transmitting by the reflective surface.

12. The optical fiber connector of claim 1 , further comprising an index-matching material within the lead-out channel portion of the optical fiber guide channel.

13. The optical fiber connector of claim 1 , further comprising a microlens within the lead-out channel portion of the optical fiber guide channel.

14. An optical fiber connector comprising:

a first fiber alignment member having a lead-in channel surface, a lead-out channel surface and a reflective surface that extends at an angle to the lead-in channel surface such that the lead-in channel surface of the first fiber alignment member is transverse to the lead-out channel surface of the first fiber alignment member; and

a second fiber alignment member that includes a lead-in channel surface and a lead out channel surface such that the lead-in channel surface of the second fiber alignment member is transverse to the lead-out channel surface of the second fiber alignment member;

wherein the first fiber alignment member is connected to the second fiber alignment member along a parting region such that the lead-in channel surface of the first fiber alignment member and the lead-in channel surface of the second fiber alignment member cooperate to form a lead-in channel portion of an optical fiber guide channel and the lead-out channel surface of the first fiber alignment member and the lead-out channel surface of the second fiber alignment member cooperate to form a lead-out channel portion of the optical fiber guide channel, and wherein the parting region intersects each of the lead-in channel portion, the lead-out channel portion and a turn portion of the optical fiber guide channel.

15. The optical fiber connector of claim 14 , wherein the first fiber alignment member is connected to the second fiber alignment member by a weld extending along the parting region.

16. The optical fiber connector of claim 14 , wherein the reflective surface is at the turn portion of the optical fiber guide channel.

17. The optical fiber connector of claim 14 , further comprising an index-matching material within the lead-out channel portion of the optical fiber guide channel.

18. The optical fiber connector of claim 14 , further comprising a microlens within the lead-out channel portion of the optical fiber guide channel.
