Idealised three-layer model optical fibres consisting of an optically dense core with the refractive index n{sub 1} surrounded by a 'holey' intermediate cladding having a much lower optical density and the refractive index n{sub 2} and by a rather thick outer cladding with the refractive index n{sub 3} are investigated. The idealised model assumes that the intermediate cladding is homogeneous. It is also assumed that n{sub 1} > n{sub 3} > n{sub 2}. It is shown that in such fibres with large differences n{sub 1} - n{sub 2} and n{sub 3} - n{sub 2}, a single-mode regime can be realised in fact, when the nearest higher modes H{sub 01}, E{sub 01}, HE{sub 21} have additional radiative losses of several hundred dB km{sup -1}, whereas the main operating mode HE{sub 11} has no such losses in the single-mode regime. It is important that the zero dispersion can be obtained in these fibres in the spectral region below 1.3 {mu}m. (optical fibres and fibre lasers)
