Fiber-optic long-period grating (LPG) operating near the dispersion turning point in its phase matching curve (PMC), referred to as a Turn Around Point (TAP) LPG, is known to be extremely sensitive to external parameters. We have developed the design optimization technique for TAP PCF LPGs employing the finite element method in a combination with the Nelder-Mead simplex method Using this tool we have designed TAP PCF LPGs for specified wavelengths and refractive indices of medium in the holes of PCF.
