| Abstract(in English) | Mode field distribution in the cladding region of photonic crystal fibers (PCF) depends strongly on the wavelength or the cladding structure. In this report, we formulate the least square approximation of the electrical field distribution of the fundamental mode (HEn mode) in PCF by a Gaussian and a hyperbolic-secant (sech) function. The analysis shows that the shape of the mode field varies with the ratio of a hole diameter d and a pitch A. The mode field is found to be approximated by a Gaussian function for large d/Λ values (i.e., for strongly guiding structure) as in step-index fibers, and by a sech function for small d/Λ values (for weakly guiding structure). |
