Abstract

A 7+1 to 1 pump/signal combiner with single-mode (SM) polarization maintaining (PM) 15 µm mode-field-diameter (MFD) signal feed-through is demonstrated. The combiner is designed for pulse amplification in an active Yb-doped airclad fiber operated in backward pumped configuration. Signal coupling through the device is realized by a microstructured taper element allowing single-mode guidance and constant MFD at a taper ratio of 3.4.
