The Impact of Fiber Core Ellipticity and Modal Coherency on Few Moded Erbium Doped Fiber Amplifiers [PDF]
39th European Conference and Exhibition on Optical Communication (ECOC 2013), 2013 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.

Co-axial dual-core resonant leaky fibre for optical amplifiers [PDF]
, 2008 We present a co-axial dual-core resonant leaky optical fibre design, in which the outer core is made highly leaky. A suitable choice of parameters can enable us to resonantly couple power from the inner core to the outer core. In a large-core fibre, such
