The use of single mode polarisation-maintaining side-hole (SMPM-SH) fibres for direct measurement of transverse force has been studied theoretically and experimentally. Based on the results of a qualitative analysis of stress distribution in such a fibre, it was predicted that SMPM-SH fibres can exhibit higher sensitivity to transverse force than a standard SMPM fibre. The modelling of two types of SMPM-SH fibres with bow-tie and round holes was conducted using finite element method and modifield coupled-mode method. It showed that while there is a marked increase of the sensitivity for the SMPM-SH fibre with bow-tie holes, the sensitivity of the SMPM-SH fibre with round holes can be even lower than that of a standard SMPM fibre. Subsequently, in an experiment, which to the authors' knowledge is the first application of SMPM-SH fibres to direct transverse force measurement, the sensitivity of an SMPM-SH fibre with bow-tie holes was measured. Measurement results agreed well with theoretical predictions. However, more systematic research is needed to determine the realisationship between the sensitivity, dimensions and geometry of the holes.
