Leaky cladding mode propagation in long-period fiber grating devices

We investigate leaky-mode propagation of the cladding modes of an optical fiber through coupling with a long-period fiber grating. A one-dimensional ray propagation model is applied. Experimental measurements are compared to a transfer-matrix model to estimate the cladding mode losses. Losses are also measured using an all-fiber Mach-Zehnder mode interferometer. The measured losses are somewhat greater than predicted by the simple theory.
