Resumen
Two optical fiber devices have been coated in parallel: a long
period fiber grating (LPFG) and a cladding-removed multimode optical
fiber (CRMOF). The progressive coating of the LPFG by means of the
layer-by-layer electrostatic-self-assembly, permits to observe a resonance
wavelength shift of the attenuation bands in the transmission spectrum. The

Two optical fiber devices have been coated in parallel: a long
period fiber grating (LPFG) and a cladding-removed multimode optical
fiber (CRMOF). The progressive coating of the LPFG by means of the
layer-by-layer electrostatic-self-assembly, permits to observe a resonance
wavelength shift of the attenuation bands in the transmission spectrum. The
cause of this wavelength shift is the reorganization of the cladding mode
effective indices. The cause of this modal reorganization can be understood
with the results observed in the CRMOF coated in parallel. A lossy-moderesonance
(LMR) is generated in the same wavelength range of the LPFG
attenuation bands analyzed. Moreover, the thickness range where the
wavelength shift of the LPFG attenuation bands occurs coincides exactly
with the thickness range where the LMR can be visualized in the
transmission spectrum. These phenomena are analyzed theoretically and
corroborated experimentally. The advantages and disadvantages of both
optical fiber devices are explained. [--]
