Abstract

Numerical Aperture (NA) is one of the fundamental properties of optical fibres. It determines the ability of efficient light coupling into the fibre and low loss splicing with other fibres. NA is essential when novel fibres are manufactured. Moreover, dispersive behaviour of geometrical guiding mechanisms, existing in microstructured fibres, is completely different comparing with material guiding mechanisms of classical fibres. Therefore we constructed measurement system, for characterization the dispersive properties of NA of specialty microstructured fibres in broad wavelength range. Additionally, presented setup can be applied for measurements refractive index of different materials (including highly absorbing) filling the holes of microstructured fibre in broad wavelength range.
