Microstructure optical fibres with a cladding consisting of a single cycle of air holes and the minimum core diameter of 1 {mu}m have been fabricated and studied. Guided modes supported by this fibre are characterised by a high light localisation degree and display the C{sub 6{nu}} point-group spatial symmetry of the transverse field distribution. A high refractive index step between the core and the cladding in the created fibres strongly confines the light field in the fibre core. The spectral broadening of low-power femtosecond laser pulses in the fibre of this type is experimentally studied. (nonlinear optical phenomena)
