Fabrication of fiber with sandpaper-abraded diffuser end. (a) The jacket and cladding are removed from the end of a 2 mm core multimode fiber. (b) The fiber core’s surface underwent abrasion with sandpaper. A blue sine wave is drawn on the paper behind part of the abraded and unabraded fiber. (c) Light diffusion is shown at the end of a 1.5 mm core multimode fiber with abrasion from sandpaper located left of the white dashed line. The surface of the sandpaper-abraded fiber core (orange box) is shown under 10X magnification.
