Abstract
A zero-dispersion wavelength (lgr/sub ZD/) below 600 nm has been predicted for a pure silica modified-total-internal-reflection (M-TIR) single-mode crystal fibre with a 1 mm pitch. The fibre is single mode from at least 250 nm, i.e., from well below lgr/sub ZD/. Both a method for designing single-mode crystal fibres using an anti-guiding structure and a fast calculation scheme for investigating the structure for different pitch sizes are proposed.
