The applictions of lensed fiber
The characteristics of the Lensed Fibers depends greatly upon the applications. For laser diode and waveguide coupling applications, beam quality is paramount. The focused spot characteristics must match the waveguide characteristics as closely as possible to ensure good coupling. In contrast, fiber to photodiode coupling does not require a high quality beam. Only one has to ensure that the focused spot size is smaller than the photodetector. Thus taper fibers for photodiode applications can be offered at a much lower cost.
