The numerically optimized Ge-doped photonic crystal fiber long-period gratings operate around the dispersion turning point on the phase matching curve of the coupled modes. This special type of LPG, referred to as a Turn-Around-Point (TAP) LPG, can be employed for evanescent broadband absorption spectroscopy or optical intensity-based refractometry
