Abstract

Long period fiber gratings couple the fundamental guided mode to forward propagating cladding modes. A Characteristic of LPGs in SMF is that their spectral properties (resonant wavelength and coupling strength) are sensitive to the refractive index of the surface surrounding the cladding region. Because of this, LPGs are typically packaged unrecoated to obtain insensitive spectral properties. In this paper the effective index model combined with the coupling-mode theory are used to study the characteristics of LPGs based on photonic crystal fiber (PCF). After plenty of numerical simulation, the results demonstrate that PCF-based LPGs will be more insensitive to the surrounding medium than those written in SMF.
