| 中文摘要 | based on the mach-zehnder effect between the core mode and the cladding modes, the interference fringes are formed by a pair of cascaded long-period fiber gratings (clpfgs). theoretical analyses show that the spectral spacing and the wavelength of these fringes are functions of the waveguide dispersion factor gamma, which is a characterizing parameter to lpfg and with theoretical and applicational significance. by measuring the characteristics of the transmission spectra of clpfgs, the absolute value of gamma can be obtained. at the same time, the thermo-optic coefficient of effective refractive index difference between core and cladding modes, p, can also be obtained by measured the temperature sensitivity of these fringes. in the experiments, \gamma\ and mu were measured by this method to be 0.874 and 4.08 x 10(-5) degreesc(-1), respectively, for lpfgs with period of 450 mum and with a he14 resonant peak at 1554 nm.
