Abstract

The non-destructive measurement of refractive-index profiles (RIP) in optical fibre preforms is of considerable importance to both preform fabrication and to fibre propagation assessment. Recently we have reported a technique based on spatial filtering which allows direct visualisation of the preform deflection function and reveals the RIP in considerable detail. The method has the advantage that it requires a minimum of equipment and is simple to apply. We report here a further development involving dynamic filtering which allows both enhanced performance and easier computer automation. The capability of the new equipment is demonstrated by using it to reveal the evolution of the RIP along the length of a single-mode fibre preform and. to predict at each point the wavelength region of monomode operation. It is shown that considerable variation can occur towards the ends of the preform and that this causes a shift of the cut-off wavelength. The method thus provides a powerful tool for preform diagnosis.
