Abstract
Radial emission optical fiber terminations that include conical elements can prevent axial emission and redirect all incident light to radial positions. One termination includes an optical fiber having an up-tapered terminus, the up-tapered terminus having a maximum taper diameter of at least 1.5 times the core diameter and ending at a cone-tip which has an apex angle in a range of about 70° to about 100°. Another termination includes a fiber cap that is a unitary construction of a glass tube and an optical element that bisects the glass tube. The glass tube includes an open end adapted to receive an optical fiber and a closed end. The optical element, consisting of fused quartz or fused silica, has an input face proximal to the open end of the glass tube and a conical face proximal to the closed end of the glass tube.
