Abstract

In this work we report a -24dB LP11 mode suppression in a 7+1 to 1 Backward Pump-Signal Combiner. The mode content is measured using the S² -Measurement technique. The high signal beam quality is attributed to a low overlap splice loss between the Tapered Fiber Bundle and the output fiber. The combiner output fiber is large mode area with a LP01 mode effective area of 584 um².
