| Abstract(in English) | In this paper the effective refractive indexes of core mode and various linear polarized cladding modes has been calculated as a function of wavelength for tapered cladding layer at which flexural acoustical waves on fiber Bragg gratings (FBGs) and the resultant superstructure modulation FBG are excited. Contradirectional and codirectional couplings induced by FBG and long period grating (LPG) and the relationship between these couplings and propagating modes through core and cladding have been examined theoretically. A comparison between the theoretically predicted reflection spectra and the previously obtained experimental results is discussed. |
