Stub having an optical fiber

1. A device comprising:

a stub having an aperture, the stub having a first end and a second end, the first end of the stub separated from the second end of the stub by a first stub length, the aperture having a conical portion adjacent the second end of the stub, the conical portion of the aperture having an apex; and

an optical fiber mounted in the aperture of the stub, the optical fiber having a first end and a second end, and wherein the first end of the optical fiber is polished so as to be substantially flush with the first end of the stub, and wherein the second end of the optical fiber is terminated at a predetermined position so as to provide for a predetermined length of the optical fiber measured from the first end of the optical fiber to the second end of the optical fiber, the second end of the optical fiber substantially adjacent to the apex of the conical portion of the aperture of the stub, and wherein the first stub length is greater than the predetermined length of the optical fiber, and wherein the conical portion of the aperture of the stub is sized so as to prevent light energy emanating from the second end of the optical fiber from impinging on a surface of the conical portion of the aperture of the stub.

2. A device comprising:

a stub having an aperture, the stub having a first end and a second end, the first end of the stub separated from the second end of the stub by a first stub length, the aperture having a conical portion adjacent the second end of the stub, the conical portion of the aperture having an apex;

an adhesive material; and

an optical fiber attached to the aperture of the stub with the adhesive material, the optical fiber having a first end and a second end, and wherein the first end of the optical fiber is polished so as to be substantially flush with the first end of the stub, and wherein the second end of the optical fiber is cleaved at a predetermined position so as to provide for a predetermined length of the optical fiber measured from the first end of the optical fiber to the second end of the optical fiber, the second end of the optical fiber substantially adjacent to the apex of the conical portion of the aperture of the stub, and wherein the first stub length is greater than the predetermined length of the optical fiber, and wherein the conical portion of the aperture of the stub is sized so as to prevent light energy emanating from the second end of the optical fiber from impinging on a surface of the conical portion of the aperture of the stub.

3. A device comprising:

a stub having an aperture, the stub having a first end and a second end, the first end of the stub separated from the second end of the stub by a first stub length, the aperture having a conical portion adjacent the second end of the stub, the conical portion of the aperture having an apex;

an adhesive material; and

an optical fiber attached to the aperture of the stub with the adhesive material, the optical fiber having a first end and a second end, and wherein the first end of the optical fiber is polished so as to be substantially flush with the first end of the stub, and wherein the second end of the optical fiber is cleaved at a predetermined position so as to provide for a predetermined length of the optical fiber measured from the first end of the optical fiber to the second end of the optical fiber, the second end of the optical fiber substantially adjacent to the apex of the conical portion of the aperture of the stub, and wherein the first stub length is greater than the predetermined length of the optical fiber, and wherein the conical portion of the aperture of the stub is sized so as to prevent light energy emanating from the second end of the optical fiber from impinging on a surface of the conical portion of the aperture of the stub, and wherein

the second end of the optical fiber is cleaved by way of laser ablation.

4. A device comprising:

a stub having an aperture, the stub having a first end and a second end, the first end of the stub separated from the second end of the stub by a first stub length, the aperture having a conical portion adjacent the second end of the stub, the conical portion of the aperture having an apex;

an adhesive material; and

an optical fiber attached to the aperture of the stub with the adhesive material, the optical fiber having a first end and a second end, and wherein the first end of the optical fiber is polished so as to be substantially flush with the first end of the stub, and wherein the second end of the optical fiber is cleaved at a predetermined position so as to provide for a predetermined length of the optical fiber measured from the first end of the optical fiber to the second end of the optical fiber, the second end of the optical fiber substantially adjacent to the apex of the conical portion of the aperture of the stub, and wherein the first stub length is greater than the predetermined length of the optical fiber, and wherein the conical portion of the aperture of the stub is sized so as to prevent light energy emanating from the second end of the optical fiber from impinging on a surface of the conical portion of the aperture of the stub, and wherein

the second end of the optical fiber is cleaved by way of a mechanical process.

5. A device according to claim 4 wherein the second end of the optical fiber is cleaved at a predetermined angle.

6. A device according to claim 5 wherein the optical fiber is made of a glass material.

7. A device according to claim 6 wherein the stub is made of a ceramic material.
