Introduction: | Singlemode, Multimode or Panda Type Polarization Maintaining (PM) fibers can be tapered. For multimode fibers, only polished versions, with a polish radius and taper angle can be produced. While they can improve coupling efficiencies when used with laser diodes or VCSELs, they do not focus to an actual spot like singlemode and PM fiber versions do. We can also generate other polish profiles , such as wedge shapes, which are useful for coupling strip laser diodes into multimode fibers. |
