Abstract: Experimental and theoretical investigations are reported of the spectral characteristics of photoinduced in-fibre refractive-index gratings for coupling the fibre core and cladding modes. A theoretical model is developed for predicting the transmission spectra of such gratings and the structure of the coupled cladding modes is considered.
