Abstract
An optical element, such as a waveguide or fiber ribbon, may be formed with an edge surface that reduces back reflections when light travels between optical elements butted against one another. Instead of cutting the surface at an oblique angle to the plane of the element, the surface may be cut transversely to this plane but at an angle to the optical axis, in order to facilitate the fabrication of an appropriately inclined optical interface.
