Design of turn-around-point long-period gratings in a photonic crystal fiber for refractometry of gases

Original language description

A fiber-optic long-period grating (LPG) operating near the dispersion turning point in its phase matching curve, referred to as a turn-around-point (TAP) LPG, is known to be highly sensitive to external parameters. So far TAP LPGs have been realized in specially designed or post-processed conventional fibers, not yet in PCFs, which allow a great degree of freedom in engineering the fiber's dispersion properties through the control of the PCF structural parameters. We have developed the design optimization technique for TAP PCF-LPGs employing the finite element method for PCF modal analysis in a combination with the Nelder-Mead simplex method for minimizing the objective function based on target-specific PCF properties. Using this tool TAP PCF-LPGs canbe designed for specified wavelength ranges and refractive indices of medium in the air holes. We present here the dispersion optimization of PCF-LPG for refractometry of gases. The resonant wavelength of an optimized PCF-LPG is subsequen
