Abstract :
The fabrication and evaluation of D-fibres, whose optical properties are compatible with standard single-mode fibre designs, is reported. The high tolerances achieved in the process of drawing a tapered preform are shown to be necessary for predicting the transverse coupling behaviour of the fibres.
