Abstract

A connector that provides alignment of an optical fiber to a photonic device. The connector has a threaded sleeve, a ferrule cavity, an aperture in optical communication with the ferrule cavity and having a center that is substantially aligned with a center of the ferrule cavity and a device cavity that is configured to receive the photonic device and further in optical communication with the ferrule cavity via the aperture.

First claim

What is claimed is:

1. A connector that provides alignment of an optical fiber to a photonic device, the connector comprising:
a threaded sleeve;
a ferrule cavity comprising a first end, an opposing second end, and a cylindrical inner sidewall positioned between the first end and the second end, wherein the ferrule cavity is configured to receive light from a ferrule at the first end, and wherein the first end of the ferrule cavity is substantially flush with a wall that is inset within the threaded sleeve, wherein a diameter of the cylindrical inner sidewall of the ferrule cavity is larger than the diameter of the ferrule;
an aperture in optical communication with the ferrule cavity and having a center that is substantially aligned with a center of the ferrule cavity; and
a device cavity configured to receive the photonic device and further in optical communication with the ferrule cavity via the aperture, wherein a center of the device cavity is substantially aligned with the center of the ferrule cavity and the center of the aperture.

2. The connector of claim 1 , wherein the threaded sleeve is configured to receive an optical fiber cable and wherein the threaded sleeve comprises a male threading.

3. The connector of claim 1 , wherein the wall is configured to abut the ferrule and wherein an inner diameter of the threaded sleeve is configured to receive a sleeve that substantially circumnavigates the ferrule.

4. The connector of claim 1 further comprising a flange that is positioned around the ferrule cavity.

5. The connector of claim 1 , wherein a diameter of the cylindrical inner sidewall of the ferrule cavity is between 2.55 mm and 6.0 mm.

6. The connector of claim 5 , wherein the diameter of the cylindrical inner sidewall of the ferrule cavity is between 2.6 mm and 3.6 mm.

7. The connector of claim 1 , further comprising a surface mount connector.

8. The connector of claim 1 , wherein the threaded sleeve comprises a notch that is configured to receive a key.

9. The connector of claim 1 , wherein a diameter of the aperture is smaller than a diameter of the ferrule cavity and wherein the diameter of the ferrule cavity is less than a diameter of the device cavity.

10. An optical system, comprising:
a photonic device; and
a connector configured to provide alignment of an optical fiber to the photonic device, wherein the connector comprises:
a threaded sleeve;
a ferrule cavity comprising a first end, an opposing second end, and a cylindrical inner sidewall positioned between the first end and the second end, wherein the ferrule cavity is configured to receive light from a ferrule at the first end, and wherein the first end of the ferrule cavity is substantially flush with a wall that is inset within the threaded sleeve, wherein a diameter of the cylindrical inner sidewall of the ferrule cavity is larger than the diameter of the ferrule;
an aperture in optical communication with the ferrule cavity and having a center that is substantially aligned with a center of the ferrule cavity; and
a device cavity configured to receive the photonic device and further in optical communication with the ferrule cavity via the aperture, wherein a center of the device cavity is substantially aligned with the center of the ferrule cavity and the center of the aperture.

11. The optical system of claim 10 , wherein the threaded sleeve is configured to receive an optical fiber cable and wherein the threaded sleeve comprises a male threading.

12. The optical system of claim 10 , wherein the wall is configured to abut the ferrule and wherein an inner diameter of the threaded sleeve is configured to receive a sleeve that substantially circumnavigates the ferrule.

13. The optical system of claim 10 , wherein the connector further comprises a flange that is positioned around the ferrule cavity.

14. The optical system of claim 10 , wherein a diameter of the cylindrical inner sidewall of the ferrule cavity is between 2.55 mm and 6.0 mm.

15. The optical system of claim 14 , wherein the diameter of the cylindrical inner sidewall of the ferrule cavity is between 2.6 mm and 3.6 mm.

16. The optical system of claim 10 , wherein the connector further comprises a surface mount connector.

17. The optical system of claim 10 , wherein the threaded sleeve comprises a notch that is configured to receive a key.

18. The optical system of claim 10 , wherein a diameter of the aperture is smaller than a diameter of the ferrule cavity and wherein the diameter of the ferrule cavity is less than a diameter of the device cavity.

19. A system, comprising:
a ferrule cavity comprising a first end, an opposing second end, and a cylindrical inner sidewall positioned between the first end and the second end, wherein the ferrule cavity is configured to receive light from a ferrule at the first end, and wherein the first end of the ferrule cavity is substantially flush with a wall that is inset within a sleeve, wherein a diameter of the cylindrical inner sidewall of the ferrule cavity is larger than the diameter of the ferrule;
an aperture in optical communication with the ferrule cavity and having a center that is substantially aligned with a center of the ferrule cavity; and
a device cavity configured to receive a photonic device and further in optical communication with the ferrule cavity via the aperture, wherein a center of the device cavity is substantially aligned with the center of the ferrule cavity and the center of the aperture.

20. The system of claim 19 , wherein the sleeve comprises a threaded sleeve that is configured to receive an optical fiber cable, wherein the wall is configured to abut the ferrule, and wherein an inner diameter of the threaded sleeve is configured to receive a sleeve that substantially circumnavigates the ferrule.
