Abstract

We report preliminary investigations on the application of the prism coupling technique to the measurement of the mode spectra of conventional and birefringent single-mode fibres (SMFs). Experimental results on the measurement of the propagation constant in normal SMF, and the application of this technique to the measurement of beat length on an elliptic-core SMF, are presented.
