The authors demonstrate that by injecting a combination of LP 11 modes in a few‐mode high‐birefringence fibres that all‐optical control of the spatial beam intensity at the fibre output is achieved by varying the polarisation at the fibre input. These results may be generalised to the cases where different and several higher order modes are employed.
