Abstract
The properties of long period gratings in Photonic crystal fibers (PCFLPGs) are systematically analyzed by the improved full-vector effective index model and the coupled mode theory. Dual-resonance peak occurs in PCFLPGs. The dependence of the strength of coupling and the resonance wavelength on the hole pitch, the relative hole size, the grating period, the length of grating, the refractive index modulation depth and the chirp coefficient is studied. Some useful conclusions are obtained, which provide the theoretical basis for the applications of PCFLPGs such as the optical fiber communication, the optical fiber sensing and so on.
