Abstract
The group velocity dispersion (GVD) characteristics of a holey fibre design with ahigh index, slot structure in the core region are modified by introducing a simplecladding structure with a few large air holes. Our simulation results show thatultra-small mode effective areas and a high nonlinearity of the TE mode canbe achieved, which is confined in the narrow slot by two silicon slabs in a glassfibre. This slot structure can be optimized to simultaneously achieve a very smallAeff and a single-TE-mode propagation. On the other hand, the proposed claddingcan significantly reduce and flatten the large negative GVD of the slotstructure, which could improve the nonlinear efficiency and interactionlength for nonlinear applications. Our results indicate that an ultra-smallAeff of0.16 µm2 and a flattened and reduced GVD with less than10 ps nm − 1 km − 1 dispersion ripple within a 40 nm range at the 1.55 mm wavelength are achievable.
