We report on the fabrication and characterisation of a Bragg grating in multimode microstructured polymer optical fibre with a Bragg wavelength of 827nm. This is the smallest Bragg wavelength reported to date for a polymer optical fibre grating and the relatively low loss of the fibre at this wavelength considerably enhances the utility of the device compared to gratings at longer wavelengths.
