Abstract
In order to solve the splice loss problem of photonic crystal fiber,the full vector model was adopted to calculate the mode field radius,air hole radius as well as its relation with doping concentration in total-internal-reflection fiber and high-nonlinearity fiber.Based on the results,the splice loss of photonic crystal fiber and single mode fiber was analyzed in detail.The calculation indicates that the mode-field unbalance is the main reason of splice loss for total-internal-reflection fibers and high-nonlinearity fibers.An appropriate modification of mode field match can reduce the splice loss to a minimum value.
