| Abstract: | A general partially coherent source field on the end of an optical fibre has been represented by a characteristic angular spectrum of independent plane waves. The launching of both trapped and tunnelling (leaky) power is investigated for both step and graded-index fibres by considering the effect of one component of the angular spectrum, using geometric optics acceptance theory. The effect of the degree of coherence on the pulse response of the fibres is briefly discussed. |
