2 Tapered optical fibers cause optical mode mixing that tends to homogenize spatial power larger input core diameter can prevent input damage and allow a smaller diameter pigtail for convenience in adapting to a wide range of optical optical fibers can be used as a passive optical component to alter the input and / or output divergence( ) with regard to an optical FIBER , as a high power coupler for laser energy, as this will spread the energy over alarger area, or simply as a device to relax tolerances in an optical system. To ensure maximum efficiency of lighttransmission, the numerical aperture ( ) of the light entering the taper input should be divided by the taperratio. As an example, assume the input core diameter of the taper is 400 and the output core is 200 , which is a2.
