The Impact of Fiber Core Ellipticity and Modal Coherency on Few Moded Erbium Doped Fiber Amplifiers

We numerically demonstrate that the few moded erbium doped fiber amplifier models based on linearly polarized and vector modes are equivalent when the fiber core exhibits slight ellipticity and the signals in the guided modes are incoherent. These conditions are fulfilled in a practical mode divisio...

Description
Summary:We numerically demonstrate that the few moded erbium doped fiber amplifier models based on linearly polarized and vector modes are equivalent when the fiber core exhibits slight ellipticity and the signals in the guided modes are incoherent. These conditions are fulfilled in a practical mode division multiplexed system.
