Abstract :
The second-order nonlinearity profile in a thermally poled special twin-hole fibre with a borosilicate ring layer around the anode hole has been characterised with second-harmonic microscopy. The induced nonlinearity was found confined to the borosilicate layer at lower poling voltages but could overcome it and reach the fibre core when the poling voltages were higher.
