Abstract
For increasingly popular space division multiplexing(SDM) systems using few-mode fibers a hybrid few-mode erbium-
doped fiber amplifier design is proposed in this Master thesis.
Modeling the amplifier and simulations are used to optimize the
coupling of both the signal and pump-source to the amplifier
and verify the compatibility of the erbium-doped few-mode fiber
with other readily available few-mode fibers. The amplifier is
fabricated and characterised using a digital holography setup to
verify its capabilities in SDM systems, and is demonstrated to
have a gain >20 dB, while maintaining a differential modal gain
of ≤2.5 dB and mode dependent loss <1.0 dB
