Abstract: The optical properties of Bragg fibers with an intermediate (matching) layer between the core and periodic microstructured cladding have been studied. It is established that the optical losses exhibit a periodic dependence on the thickness of the matching layer, which is related to the presence of resonances and anti-resonances in this layer. It is demonstrated that the transmission spectra of Bragg fibers can be controlled by varying the parameters of the internal (matching) layer of the cladding.
