All-silica photonic bandgap fibre with zero dispersion and a large mode area at 730 nm
A theoretical analysis of a photonic bandgap fibre, consisting of a pure silica background with a triangular lattice of Ge-doped high-index rods, is presented. This novel fibre design guides a single, well-confined mode in a core region made from undoped silica. The fibre is found to have positive waveguide dispersion, which may be used to shift the zero-dispersion wavelength down to 730 nm, while maintaining an effective mode area of 17 $mu@-m$+2$/.
This is an order of magnitude larger than what may be achieved in highly non-linear index-guiding microstructured fibres with comparable zero-dispersion wavelength.
