Abstract

A novel mode converter which is based on long period fiber grating (LPFG) is proposed. A graded-index optical fiber is introduced to induce strong mode coupling at wide bandwidth. By optimize the fiber configuration and parameters, and the appropriate choice of grating parameter, high mode conversion efficiency with cross-talk lower than -20 dB and wide operation bandwidth over 180 nm can be achieved.
