Pump and signal power combiners for high-power fiber amplifiers applications

Abstract

In this work we present our result on investigation of pump power combiner fabrication process in configuration (N+1)x1. Our fabrication method is based on tapering of fiber bundle consisting of 6 multimode fibers and one signal fiber. We present results on fabrication power combiners based on single mode fibers and large mode area fibers for the signal. Full Text: PDF References D.
