Recent progress in microstructured polymer optical fibre fabrication and characterisation is reported. A wide range of different optical functionalities can now be obtained by modifications of the microstructure, as demonstrated by the fibres presented. We discuss the fabrication issues associated with certain types of fibre, and present microstructured fibres that show 10X10 multichannel guidance for image transmission and interconnect applications, and single-mode suspended core fibre for supercontinuum generation. Clearly, microstructured polymer optical fibres are an exciting new development, offering opportunities to develop new fibres for a wide range of applications.
