Large mode area silicon microstructured fiber with robust dual mode guidance
Optics Express, 2009 A silicon microstructured fiber has been designed and fabricated using a pure silica photonic bandgap guiding fiber as a 3D template for materials deposition. The resulting silicon fiber has a micron sized core but with a small core-cladding index contrast so that it only supports two guided modes.

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

Modeling of transverse mode interaction in large-mode-area fiber amplifiers
Optics Express, 2008 We model the transverse mode interaction in a large-mode-area fiber amplifier by solving the Fresnel wave equation including local gain saturation. In order to calculate the electric field distribution we apply a finite difference beam propagation method, which is followed by the derivation of the modal powers and modal polarization states.
