Abstract :
We propose a new method for determining equivalent-step index fibres: the far-field intensity halfangle is measured for a range of wavelengths and the data fitted by the step-fibre formula. A simple analytical formula aids the analysis. Proven experimental techniques can be used and no Gaussian or other theoretical approximations are involved.
