This report results from a contract tasking Crystal Fibre AS as follows Crystal Fibre AS will develop a tapercoupler solution to interface between a new polarization maintainingpolarizing amplifier fiber DC-200-35-Yb-PM and respectively pump fibers and a signal input fiber. The anticipated intermediate interface will be a 250 micron0.46 NA pump guide and 20 micron MFD PM signal core fiber. We will seek to further interface this fiber to a tapered fiber bundle with either 100 or 200 micron pump fibers and a polarization maintaining signal input fiber. It is the goal to achieve an interface with 6 multi-mode pump input ports consisting of 200220 0.22 NA fiber with a polarization maintaining 20 micron core signal feed-through capable of single-mode operation at 1064nm. In case this is not possible a fallback solution will be 6 or more multi-mode pump input ports consisting of 105125 0.15 or 0.22 NA fiber with a polarization maintaining 7 micron core signal feed-through capable of single-mode operation at 1064nm. Two fiber amplifier sub-assemblies including the developed components and an appropriate length of active fiber 3-4 m will be delivered at the end of the project.
