キーワード:Fibers for space division multiplexing, Fiber gratings, Fiber/waveguide amplifiers and laser

We propose the mode dependent gain (MDG) reduction technique in few mode fiber amplifier using trench assisted GI fiber type long period grating. 1.8dB MDG reduction and wideband mode scrambling over 100nm are experimentally obtained.
