Abstract
In this work, the modal transition induced by lossy mode resonances has been analyzed as a function of wavelength for thin-film coated cladding removed fibers. The wavelength dependence of the modal structure allows us to explain the resonance phenomenon. The numerical data obtained were calculated with a method based on the exact calculation of core modes. Theoretical simulations have been compared with experimental results showing good agreement.
