Abstract
In a long period grating (LPG) made on a silica-based single material photonic crystal fiber (PCF), the effect of material dispersion on the resonance wavelength of the LPG is negligible. The resonance wavelength, the period and length of the LPG, and the diameter and pitch of the air -hole lattice of the PCF are found to obey a scaling law. Simulations show that the resonance wavelength has a non-monotonic dependence on the grating period and, for a particular grating period, there could exist dual resonance wavelengths and hence double transmission dips due to phase matching between the fundamental core mode and a cladding mode simultaneously at two wavelengths. This phenomenon may be explored for novel devices and sensor applications.
