We report on a novel dispersion compensation technique using the LP02 mode of a ring-core dispersion compensating fiber along with a compact mode converter based on hollow optical fiber. Design parameters of both the mode converter and the matching dispersion compensating fiber are numerically analyzed. Evaluation of mode conversion efficiency, total dispersion, dispersion slope, and modal delay are discussed. It is predicted that 1.31 km of proposed dispersion compensating fiber can compensate the chromatic dispersion accumulated in 60 km conventional single-mode fiber with the average dispersion below ±1 ps/nm/km in the entire conventional band, 1.53-1.57 μm.
