Samenvatting

We demonstrate a few-mode erbium-doped fiber amplifier employing a mode-selective photonic lantern for controlling the modal content of the pump light. Amplification of six spatial modes in a 5 m long erbium-doped fiber to x223C;6.2x2009;x2009;dBm average power is obtained while maintaining high modal fidelity. Through mode-selective forward pumping of the two degenerate LP21 modes operating at 976 nm, differential modal gains of lt;1x2009;x2009;dB between all modes and signal gains of x223C;16x2009;x2009;dB at 1550 nm are achieved. In addition, low differential modal gain for near-full C-band operation is demonstrated.
