1. A radial emission optical fiber termination comprising:

  • an optical fiber that includes a fluorine-doped-silica clad, silica core fiber which has a core diameter;

    the 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, the up-tapered terminus having a length in a range of about 3 to about 20 times the core diameter;

    the up-tapered terminus ending at a cone-tip which has an apex angle in a range of about 70°

    to about 115°
