We present a new approach to the design of the holey fibers that have ultra-high nonlinearity and dispersion properties optimized for tunable fiber parametric wavelength converters based on degenerated four wave mixing. This hybrid approach combines downhill simplex algorithms with four wave mixing modeling. Exploiting the relations between fiber properties and the converter's characteristics, this method is not only much faster than other methods proposed before but also enables an inverse design of the holey fibers according to the pre-set device characteristics, like conversion gain, tuning range, fiber length and pump power. We then investigate the sensitivity of these characteristics to the small variations in the fiber structural parameters and find adjusting the pump power can to some extent mitigate the impact of the fabrication errors.
