D-shaped glass fibres have been periodically poled using standard planar lithography to define the patterned electrode and applying high voltage at elevated temperature. The resulting nonlinear gratings, uniform over 75 mm have been used for efficient second-order nonlinear frequency conversion. Efficiencies of ~1% have been achieved with demonstrated potential of several 10s %
