摘要：

A mechanical mode converter for mode division multiplexed systems over SSMF at 850 nm is proposed and evaluated experimentally by the transmission of OOK-modulated optical signals. The proposed mode converter is based on a periodic structure defined by the grating period (Lambda) parameter and the number of mode coupling points, N. A mechanical grating with N=50 points and a tunable grating period (Lambda form 440 to 456 mu m) has been designed offering a 124-nm tuning bandwidth. The LP01 mode to LP11 mode conversion has been experimentally assessed and a conversion efficiency of 89 % has been achieved in the designed device. Optical transmission of OOK-modulated signals with 1.25 and 2.5 Gb/s bitrates on LP01 mode or a converted LP11 mode is demonstrated achieving BER < 10(-9) after 1-km optical transmission over SSMF at 850 nm.
