Paper Abstract

All-fibre acousto-optic frequency shifters have in the past been based on two-mode fibres1,2,3, the frequency- shifted light appearing in the second of the two modes. Mode convertors and filters are necessary to separate the residual carrier from the shifted signal and give a single-mode output.
