1. An apparatus, comprising:
- an optical fiber including a surface non-normal to a longitudinal axis of a distal end portion of the optical fiber, wherein the surface defines a portion of an interface configured to redirect electromagnetic radiation propagated from within the optical fiber and incident on the interface to a direction offset from the longitudinal axis; and
a doped silica cap, the doped silica cap being fused to the optical fiber such that the surface of the optical fiber is disposed within a cavity defined by the doped silica cap.

Abstract
In one embodiment, an apparatus may include an optical fiber that may have a surface non-normal to a longitudinal axis of a distal end portion of the optical fiber. The surface may define a portion of an interface configured to redirect electromagnetic radiation propagated from within the optical fiber and incident on the interface to a direction offset from the longitudinal axis. The apparatus may also include a doped silica cap that may be fused to the optical fiber such that the surface of the optical fiber may be disposed within a cavity defined by the doped silica cap.
