We have fabricated 7‐cell and 3‐cell core hollow‐core photonic bandgap fibres with core sizes ranging from to 6.5 μm. A numerical study of the nonlinear coefficient of fibres with different core sizes is carried out. We show that the nonlinearity is more effectively increased by a 3‐cell core design than by reducing the size of a seven‐cell core.
