| Abstract: | By use of scalar approximation of three - layer model, we performed the numerical computation of effective refractive index of cladding modes of long period fiber gratings, analyzed the relationship between resonant wavelengths and grating period, and drew a conclusion on the dependence of resonant wavelengths with respect to the varying refractive indices of environment. |

| Keywords: | long period fiber gratings cladding modes resonant wavelength |
