| 摘要 |
In one aspect, the invention is an optical fiber having a modified geometry. The optical fiber includes an optical fiber portion. The optical fiber portion can have a first fiber end face and a cylindrical fiber surface encircling the first fiber end face. The optical fiber having a modified geometry also includes a contoured surface formed from the first fiber end face. The contoured surface does not extend beyond the cylindrical fiber surface. A reflective coating disposed on the contoured surface and an optical transmission region formed from a portion of the cylindrical fiber surface are also included in the optical fiber having a modified geometry.
